Finessing the 'Muppets'

Max Ivins discusses how Look FX helped refine Jim Henson's beloved furry friends for their big-screen comeback.

No, they didn't mess with the Muppets by going CG. But Look FX did do a lot of blue screen work because Kermit's green, of course. They didn't want to carry around two sets of screens.

"The one-word description I would use is 'finesse,'" suggests Max Ivins, the VFX supervisor for Look FX. "This is not a brute force, tour-de-force use of CGI. It was a finesse job of how to get those hairs from the Muppets back into the shot. And also how to roto out and get rid of all those puppeteers heads and everything else that's out of place. There were some pretty incredible rig set ups to enable the puppeteers to do their thing that in the past you wouldn't have seen."

For instance, there's a scene where Beaker runs around in circles and, considering that he's less than half a foot tall, they built a carousel with a platform on top so the puppeteers could hide below Beaker and get him to perform convincingly. There was a grip that spun the carousel with the four puppeteers on it.

Part of the challenge of the roto work was keeping the fine details of the puppets in tact.

"They went all out to make these rigs so these things could be done, so in that sense, it's a traditional visual effect show," Ivins confirms. "It wasn't about making three-dimensional puppets and animating in CG at all. Our main mission was to enable the puppeteers to do cool things. This was much more satisfying than trying to Mupp around with them."

In fact, it's getting to the point where they can just about roto out everything. "It strikes me as very similar to a lot of what we did on Captain America," Ivins continues. "We were given a bunch of shots of him on greenscreen or on a motorcycle completely over green, and we built the backgrounds and compositing him into it or driving away from giant explosions. And this was another economical way of shooting in a studio rather than going on location, so we did set extensions and bluescreen composites."

The new Muppet Walter is introduced in an action filled dance number.

But there's definitely a lot of action and dancing in The Muppets. In the opening dance number where we're introduced to Walter, the new Muppet, he's very active. He climbs up on a dresser and jumps onto the door knob and flies through the kitchen, resulting in cereal spilling all over. That was pretty much head to toe, full-body puppeteering. "All of it was shot to backgrounds that they had shot for it and then you played that back for the puppeteers," Ivins explains. "And that gave them the freedom to do more, wearing these blue costumes. And our joke was that made them invisible."

And that freedom was important for them to more with the Muppets without having to resort to post CG, according to Ivins. But the most challenging sequence was a musical number called "Pictures in Your Mind" when Kermit walks through his mansion and there are portraits of different Muppet characters on the wall and as he goes by them they come to life and talk to him. Unlike everything else, which is supposed to be tangible, these were transitions from digital paintings that Look FX made from the characters and the scene they were in.

"And then transitioning to them as live puppets was a creative challenge that had a lot of tweaking and subtlety to it," Ivins says. "We didn't want it jumping out at you and feel digital. We worked a lot on that sequence, massaging it to get the right look."

The crowd coming out to support The Muppets needed to be massive.

There were also several traditional driving shots. "But the most interesting shot in the movie for us was when they pulled a Rolls Royce out of a lake and they needed it to look like it was rolling up onto Cannes beach. They shot set up an elaborate rig on a sled with all the characters and the actors in it and pushed it on a stage, and then we tracked them into it and then we put a big matte painting of Cannes beach behind them. Having them drive out of the Atlantic Ocean was pretty fun."

Look used Maya for the 3D and Nuke primarily for compositing along with a touch of After Effects. And they used NVIDA Quadro graphics cards. There were lots of crowd scenes along Hollywood Blvd. and inside the movie theater where the climactic telethon occurs.

Overall, Ivins says The Muppets experience reaffirmed the primacy of puppeteering.
