See James Gunn do one final dance as Groot in Guardians of the Galaxy 3

Back in 2015, before writer-director James Gunn was at the center of every superhero universe, he revealed something about Guardians of the Galaxy fans have hung onto ever since: The little dance that baby Groot does in his pot at the end of the movie was modeled on Gunn himself. “I was too embarrassed for anyone to be there,” he told Yahoo, “so I made everyone leave the room and I set up a camera and I videotaped myself dancing. Then I sent the video to the animators and had them animate over that. I begged them not to leak the video!”

Gunn shook off the shame (literally!) for 2017’s Guardians of the Galaxy 2, and he personally posted a video of him originating all of Baby Groot’s dance moves from the movie’s opening musical sequence. And to finish the trilogy off in style, he created the moves for adult Groot in Guardians of the Galaxy Vol. 3. A new video provided exclusively to Polygon by Oscar-winning VFX studio Framestore shows off a lot of what the company did behind the scenes, from animating the elaborate space city of Knowhere to producing versions of Rocket Raccoon at six different ages to laying adult Groot’s heavy tree muscles over Gunn’s dance moves.

Among many other things, the video shows footage of James Gunn’s brother Sean Gunn in a motion-capture suit, playing the on-set version of Rocket and interacting with the mocap-suited cast members who play Rocket’s experimental-animal family in the movie — robot-armed otter Lylla, spider-legged albino rabbit Floor, and wheeled walrus Teefs. But when James Gunn dances as Groot, he doesn’t wear a mocap suit. Why?

Montreal-based Framestore VFX supervisor Stephane Nazé explained to Polygon that Gunn’s performance as Groot isn’t a mocap performance — it’s
