I don't know how tall he is -- I think Bill Bixby was kinda short, but that doesn't mean what he turned into was considered short -- but IOA really, really, really needs the Hulk walking around -- or, shall I say, stomping around?
None of that CGI fake muscle stuff from the movie, either. Hire some guys with some muscles, paint 'em green, have whoever does the tall guys on stilts eyes over at the Mummy ride do some green action in the eyes, and let 'em go.
