Jimmy Fallon's Virtual Wonderland:

The Holiday Special That Shouldn’t Have Worked

The sets were virtual – the pressure was not.

“We delivered ‘final pixel’ in-camera—no post-compositing anything. What we shot is what aired.” – Kara Vedder It still sounds impossible: an NBC musical with a dozen celebrities, a dozen unique environments, and just three days to shoot it. But this high-stakes collaboration became a master class in choosing creative freedom over fear.

NO POST, NO PROBLEM

Making ‘Final Pixel’ Delivery Possible

When holiday magic looks suspiciously like a crane swinging over a blue hallway

“Everyone showed up for me.”

“The label asked, ‘Hey, would you do a holiday special if NBC wants to do it?’ I go, ‘Yeah! Let me ask.’ And of course NBC is like, ‘We love it! Let’s do it.’ And I’m like, ‘Oh, here we go!’ So then you have to make the phone calls again. I really don’t like asking people for favors, but for this album I called in every favor — and everyone showed up for me. 

Then they were like, ‘We need one more big ending.’ So I go, ‘Why don’t I fly through the air and land on the roof of 30 Rock? We’ll have the Rockettes up there, I can sing on top of New York City, and we’ll make it festive.’ So we did it — and it turned out beautiful. We used drones. It was the coolest thing ever. Honestly, it was the most holiday I’ve ever celebrated so far. It was great.”

– Jimmy Fallon on the ‘Spectacular,’ as told to Forbes

From the outside, it looked like Christmas as usual: celebrities, confetti cannons, too much velvet. But this one came with a twist: there would be no ‘just fix it in post’ – no margin for error.

Twelve celebrities, twelve sets, twelve synchronized video feeds. Three tracked cameras, real-time live compositing, with final-pixel masters handed off at wrap. And it all had to happen in three days. That’s four celebrity performances a day, in environments no stage could hold, swapped faster than a lighting cue. Math that makes producers check their blood pressure.

The miracle was that it worked so cleanly that NBC could air it as-is.

This installment of Reel Histories cuts to the human hustle behind NBC’s virtual breakthrough: the Zen-like producer gaff-taped to his phone, the DIT who hasn’t blinked since Monday, and Alex, hanging a net of sensors like Christmas lights on a tree only he can see.

ACT 1 – ASSEMBLE THE ELVES

This wasn’t a holiday special so much as a stress test in a sequinned sweater — angels in headsets making it sparkle like Rockefeller Center.

Bill Bracken:

I had been with Brad Lachman Productions for 30 years — we always did the annual televised events for Macy’s 4th of July Fireworks Spectacular, Macy’s Thanksgiving Day Parade, and Christmas in Rockefeller Center. When Brad retired, I let the producers in my network know I was available, and Jesse Collins was one of the first to reach out.

We had worked together on Macy’s Fourth of July show. He said, ‘NBC is making me the producer, and I’d love for you to be my head of production.’ The following year, Jesse signed on to produce Jimmy Fallon’s Christmas Special for NBC and brought me in.

“You won’t go wrong”

Bill Bracken:

We did a lot of searching when we were back in New York doing the Fourth of July show, but stages didn’t have the Unreal Engine technology. They had the big LED screens — they look just like Unreal Engine Technology, and you can put whatever background you want behind them. 

But what we were really looking for was the total package, with a green screen where you can create immersive environments you can really walk through and feel like you’re actually on set.

Not many companies in New York or LA do it — it’s an emerging technology. So I called Tad Scriptor, a very smart guy who is a tech manager for the Oscars and has helped design the Dolby Theater for many years. Tad told me he had worked for a company called Cobalt. He said, ‘They’re in Upstate New York, they’re lovely people, they’re immersed in this technology. You won’t go wrong.’

We had a call with Alex and Kara, and they sent us some very helpful demos. We were able to find two other companies utilizing Unreal Engine, but we felt that Alex and Kara had a real commitment to this technology. They had all the gear. Once we established that Cobalt could bring its technology to Manhattan, we knew we could put all this together.

Bill Bracken:

It really was the people. A big part of our business is connecting with people, engaging their interest, gauging their expertise. So it didn’t take us long to recognize Cobalt’s expertise and deep interest in the project. We booked a stage in Brooklyn with the largest green screen we could find, although we had to paint it blue due to the Christmas trees.

Drew Finley, who’s based here in Los Angeles, created all of our backgrounds. We had worked with Drew on the 75th Emmy Awards to recreate classic sets like Archie Bunker’s living room and the bar from Cheers. Drew made them look real with just one or two practical pieces for talent to engage with. Drew did everything else. 

Drew’s expertise and Cobalt’s technology were really a good fit.

For the Emmy Awards, it wasn’t Unreal Engine — we used an LED volume with Drew’s backgrounds. When Tad referred me to Cobalt, Jesse and his Head of Production, John Wehage, were familiar with the technology, but it was completely new to me. 

Alex and Kara were instrumental in teaching me about it.

Alex Fernbach:

It basically allowed the writers to go crazy and not edit their expectations due to budgets or locations. If they wanted a snowfield, if they needed a hardware store, if they needed a hall with a lot of doors as the overarching magical concept, if they needed the Jonas Brothers in a snow globe, or if they needed a cabin in the northwest where Justin Timberlake’s piece happened, that could all be done.

And it could all be done handily. It’s a lot less expensive to build these environments in computer graphics than it would be practically. From the moment the decision was made to produce this using virtual technology, it liberated the writers and creatives at Jesse Collins to concept with complete abandon.

Once we were on set, if changes needed to be made — if we needed more decoration in the magical hallway, for example, or more snow falling outside the hardware store — we had an on-set team of CG artists led by Drew Finley to implement those changes.

Bill Bracken:

The Christmas album is all original songs — no standards. To support Jimmy’s storytelling with very few limitations was the challenge. It ended up being a one-hour Christmas special with 12 songs and 12 different environments.

Bill Bracken:

Jimmy had spent several years creating this Christmas album, and he didn’t want a traditional Christmas special. I still remember that first Zoom meeting with Jimmy, the writers, Jesse, Dion Harmon, Janae Rosenthal, the executive producers, and me. Jesse pitched his vision to Jimmy, walking him through the entire show from start to finish — Jimmy didn’t say a word the whole time. When Jesse finished, Jimmy stood up and gave him a standing ovation.

A great example is the song Chipmunks and Chestnuts. ‘Jimmy and his team would love to have 1000 animated chipmunks on the set.’ That wasn’t possible, but we were able to place virtual chipmunks in the 3D background and stuffed chipmunks in the foreground. 

And it went on from there.

Alex Fernbach:

Take the hardware store, for example. A practical set would have occupied a large percentage of any studio. Not to mention time. 

The amount of time and labor required to build these sets would have been substantial. And lose the benefits of on-the-spot flexibility. It was a lot more efficient and creatively liberating to build the sets in computer graphics.

ACT 2 – MORE SLEIGHBELL

The shoot unfolded like a shaken snow globe with writers lobbing new gags like snowballs, hot off the printer, and the team popping out new sets like Pez.

Alex Fernbach:

We had an amazing lighting team. I think they put about 40 or 50 computer-controlled fixtures up on the grid just below our constellation — our tracking marks.

Imagine a U-shaped, 3,000-square-foot shooting proscenium. It was a three-wall blue screen, about 50 or 60 feet deep and wide. All of the shooting was supposed to happen in that space.

So, every environment had some unique flooring: a roll of linoleum, a collection of rugs, a wood floor, and a carpet down the hallway. We marked where those discrete floorings lived on the blue floor. Then the props came in and were positioned to coexist with the virtual set.

The lighting department programmed cues for each scene into the computer system. So once we had rehearsed, we could save those lighting cues. We could light, say, the magical hallway, then bring in an exterior snow scene, then the hardware store — and each was memorized and recalled at the push of a button.

It was almost military precision.

“It didn’t raise an eyebrow.”

Kara Vedder:

In the rehearsal, the props are marked just like in a theatrical performance, so the actors knew where everything would be, even though the walls weren’t there.

I always compare it to a black-box theater. You’re not building the practical sets — you’re staging them and performing live. The crew in black runs things in and out, seamlessly.

Alex Fernbach:

Beth, the director, is a seasoned veteran of three-camera shows, often live. She was actually live-switching her monitor while the performances were happening, making sure she had the coverage she needed. It was her normal workflow — nothing about the new virtual methodology changed her process.

Her directing style was identical to Saturday Night Live: three cameras, live-to-tape. For her, it was transparent. It didn’t raise an eyebrow.

Bill Bracken:

Beth is used to working fast. She used to direct SNL — she knows Fallon, and she has the skills to capture the comedy and the action on three cameras. The writers kept refining the material right up until the end, which meant we had to stay nimble.

Kara Vedder:

The big savings came from delivering ‘final pixel’ in real time. Not only were we recording the live composite, we were also recording the raw camera feed, the background, and the matte — so if something needed to be changed in post, you had all the elements.

For this project, there was no post-compositing anything. What we shot is what aired. The story was already told.

Alex Fernbach:

The beauty was that the process was non-stressful. Just different. A lot of thought went into pre-production, which made the critical path smoother. At the end of it, you had a fully composited, fully rendered, editable bunch of assets.

Fewer surprises. More control.

Kara Vedder:

That also extends to the amount of time it takes to build, light, shoot, break it down, and set something else up — however many times.  

The crew hours involved and renting the space – multiply the cost, or compromise the quality.

Alex Fernbach:

The audience senses the shortcuts – a cheap set takes you out of the moment. With virtual sets, we could give NBC something photoreal, with wide shots, with choreography, with feet on the ground. We weren’t trapped in medium close-ups like in an LED volume. That was the liberation.

Kara Vedder:

Every now and then, you need to see their feet.

Alex Fernbach:

Unbound to an LED monitor, the cameras were free to wander — on dollies, on cranes. Drew built ample set elements so Beth had what she needed on the spot.

Kara Vedder:

Pulling off those changes so close to your shoot date is an accomplishment.

Alex Fernbach:

Andrea, the Art Director, did an amazing job integrating the props and communicating with Drew to ensure there was harmony between the practical props and the virtual environment. 

So instead of building sets, you’re paying CG artists. But the total cost is significantly less.

Kara Vedder:

You’re saving a lot of money, but the timeline and production pipeline have shifted, so you spend more time and budget in ‘pre.’

Alex Fernbach:

Then, it doesn’t cost much more to build an opulent castle than it does to build a two-wall office with Venetian blinds. There’s no reason to settle for a chintzy two-wall set anymore.

We’ve done everything from gothic slashers to 1914 Paris. Anything can be done. This production was ambitious — three tracked cameras. But for a typical shoot with one or two cameras, it’s cost-efficient, with creative benefits that outweigh the old ways.

Once you’re in the land of virtual, the limits fall away.

ACT 3 – WELCOME TO TINSEL TOWN

Think air-traffic control at the North Pole: Weird Al, The Roots, and a Roots cover band played by fourth-graders landing in the same six-hour window – without a single crash.

Bill Bracken:

At first, Alex wasn’t sure we could pull it off, because The Tonight Show Starring Jimmy Fallon’s shooting schedule left only three days for us to shoot this.

Alex Fernbach:

Bill put together an astonishing team of people, and he was a champion of organization, delegation, and clarity of communication.

Bill Bracken:

I always had faith that this would work because of the team we had put together. Kara Vedder The lighting crew and the stagehands were amazing.

Alex Fernbach:

Yes – and we flew people in from LA. There were three engineers, each working on one of three cameras — two on dollies and one on a crane. The engineers could speak directly to the three camera operators and alert the camera assistants if there were any issues.

Drew brought four CG artists. Hartman’s TV Tech team networked the cameras. We had three engineers, each handling one of three cameras. Plus, a dolly grip, a crane operator, and a DIT handling twelve streams of video.

And then we had technical communication between the virtual production systems — since there were three, they all had to talk to each other.

So, if you add that to the three dolly grips and the crane operator, we had about 20 to 25 people. Hartman had a few more, including a DIT handling 12 streams of video. And it was all final pixel, because the production didn’t want to deal with massive amounts of unnecessary data in post, given the time constraints.

Beth, the director, is a seasoned veteran of three-camera shows, often live. She was actually live-switching her monitor while the performances were happening, making sure she got what she needed.

She was editing on the fly — basically a paper edit — making sure she had the coverage she was used to.

And that’s the huge point: for the director, there were no compromises.

It was exactly like her traditional way of doing SNL: three cameras, live-switched. Only here it was live-to-tape.

This new production modality didn’t even raise an eyebrow. It was completely transparent. 

Kara Vedder:

It was intuitive. Beth’s workflow and directing methodology were identical, except the work progressed more efficiently. From the outside, it looked chaotic — twelve sets in three days. But inside the workflow, it was smooth. The energy was gleeful.

Everyone experiencing it for the first time was blown away.

“This is why we do this.”

Alex Fernbach:

That moment for me was on day one of shooting when we were switching sets and I saw Bill’s smile, and Beth’s joy – working as if nothing was out of the ordinary.

Kara Vedder:

It doesn’t always get said, but for me, it’s knowing that we save them a ton of money without putting limits on the creative. Whatever they came up with, it could be done.

Alex Fernbach:

Beth, live-switching, made sure she had every angle covered so NBC got ‘final pixel’ at wrap. No re-compositing, no bottlenecks.

Alex Fernbach:

Anything you produce in computer graphics can be more realistic, photorealistic, and enabling than a bare-bones practical set, which may limit you to close-ups and medium close-ups as opposed to seeing your musical in a wide shot. It’s like going to a theater and seeing a performance on a screen from the waist up. It makes no sense. So Bill’s predilection to consider an alternative production modality was spot-on. 

Bill Bracken:

It’s not a one-size-fits-all solution, but given the material, story, and the nature of the music that Jimmy and his team created, it was a perfect fit.

One thing that helped sell NBC and Fallon’s team on the idea was a demo Alex and Kara created. It showed a performer walking through multiple rooms, vacuuming, and when you compared the raw footage to the final composite, it was astonishing. That proved what was possible and helped get the whole project off the ground.

Alex Fernbach:

It’s like when film shifted to digital. At first, everyone was afraid images would look like a surveillance camera at 7-Eleven. But once they saw the results, they never went back. Virtual production is the same. Once you see it, the paradigm shift is inevitable.

Bill Bracken:

Seeing it on paper is one thing. Walking in, you might think, How is this going to work? But once you see it on a monitor, everything starts to click.

Alex Fernbach:

It was also fascinating to see how Bill handled all the disparate elements that go into a production of this size and caliber. 

Since NBC wanted ‘final pixel,’ we put together a bulletproof camera system. With the show’s complexity, you want something proven to deliver predictable, dependable results. 

We went with the SONY platform that delivered high quality HD resolution footage. Our VP platform and all its components integrated beautifully with SONY’s platform, and we had four identical camera packages that could be swapped out instantly as a failsafe.

So the challenge wasn’t how to apply the bleeding edge virtual technology. Sometimes the best solution is ‘retrotech,’  like using a mirror. Apollo 11 was looking for gaffer’s tape and coat hangers. It wasn’t a 3D printer that saved the day – it was common resourcefulness and a history of dealing with these kinds of problems on the fly.

Kara Vedder:

Bill, what would you say this production proved for you?

Bill Bracken:

I think it was just the power of pulling together the right team – Cobalt, Drew, Beth, Andrea, lighting, props – everyone contributed. The writers kept refining the material right up until the end, which meant we had to stay nimble. 

Having such a strong collaboration made that possible.
