While its hard to fathom anyone else in the role of Star Lord other than Chris Pratt, if the Parks And Recreation star hadn't filled the role, it would have gone to another comic actor and master of the night(man). In a profile for GQ Magazine, GOTG director James Gunn admitted that if he hadnt already decided that Chris Pratt was right for the part, then he would have hired It's Always Sunny In Philadelphia star Glenn Howerton instead. As the director explained, "Glenn came along a bit later, but there was a good chance that, if I didnt cast Chris, that I wouldve cast Glenn Howerton in the role." Actually, it's a little bit shocking that Marvel didn't jump on the chance to cast Howerton. Especially after seeing his truly spectacular performances as both Danny Glovers Roger Murtaugh and Mel Gibsons Martin Riggs from the Lethal Weapon series in It's Always Sunny. This guy is a born action star! https://www.youtube.com/watch?v=wjhV1DavSRM What other Marvel what ifs would you like to add to the list? Let us know in the comment section below.
