James Gunn's new Suicide Squad movie has a massive cast and plenty of big names to go around between familiar faces like Margot Robbie's Harley Quinn and newcomers like Bloodsport and Peacemaker (played by Idris Elba and John Cena, respectively). But one name on the cast list piqued the interest of many fans--fan-favorite Taika Waititi has been signed onto the project in a mystery role for months.

First, many guessed that Waititi would be voicing King Shark, a giant, anthropomorphic man-eater in board shorts who would definitely be hilarious with Taika's familiar New Zealander accent, but Gunn himself squashed those rumors early on. He explained that he had actually got Sylvester Stallone to do the voice acting for King Shark, so fans would have to keep guessing.
