Thor: Ragnarok stormed its way into theaters nationwide last weekend, and of all the new characters introduced in the film, few have received as much adoration as director Taika Waititi's stone man Korg. However, that was hardly the end of the filmmaker's motion-capture performance in the Marvel Studios sequel.

"I am one of the heads on the three-headed alien, this character called Haju [this may not be correct spelling]," Waititi told Empire. "I'm the head on the right. And I'm also the motion-capture for Surtur," the fire demon from Muspelheim who's voiced by Clancy Brown.

Still, despite his numerous duties, Waititi continued to put in work in front of the camera even when some of the film's stars had already headed home. After Mark Ruffalo wrapped production, Waititi stood in for the Hulk during some pick-up scenes.

In playing Korg, Waititi becomes the second director of a Marvel Studios production to play a major role in his own film. Jon Favreau was the first, debuting as Happy Hogan in 2008's Iron Man.

In theaters nationwide, director Taika Waititi’s Thor: Ragnarok stars Chris Hemsworth as Thor, Mark Ruffalo as Hulk, Tessa Thompson as Valkyrie, Tom Hiddleston as Loki, Cate Blanchett as Hela, Jeff Goldblum as The Grandmaster, Idris Elba as Heimdall, Anthony Hopkins as Odin, and Karl Urban as Skurge.
