If Duhamel, Hirsch and Phillipe are the frontrunners, I'd definitely go with Phillipe. I've yet to see Duhamel play anything close to a complete character in a film. He's usually just sort of "there." Hirsch is really good but he doesn't physically suit Hal. I hate to go the "he's too short" route, but this is one case where he absolutely is. He might be okay for Kyle Raynor though. Phillipe, while not my first choice for Hal, is a very solid actor and can play a hero, a womanizer, and a badass. I think that he could do really well in this role, however I think he'd be better suited to a darker superhero character. Not sure who though.
