After many fans were convinced Nathan Fillon was playing Arm-Fall-Off-Boy in the movie, James Gunn recently debunked that theory. Tons of new characters are joining the cast this time around, with Taika Waititi, Michael Rooker, David Dastmalchian, Pete Davidson, Peter Capaldi, Sean Gunn and Storm Reid coming on board, just to name a few. Joel Kinnaman’s Rick Flag, Jai Courtney’s Captain Boomerang and Viola Davis’ Amanda Waller are also reprising their roles.
