Ha! that's awesome. There's a profile of Billy Mitchell in the latest Harper's, of all places. It seems to suggest that either his relationship to the camera, or the filmmakers, or his own self-manufactured mythos, made him seem more villainous in the film than he really is. It didn't suggest that he's actually above manipulating things to his advantage, but the author of the piece did not believe he cheated on the Donkey Kong video tape.
