Hal's character is too straight laced to be played by Reynolds.
i never liked the super straight laced portrayal of the character. he was just a green superman.
i prefer when they push the more daredevil (adjective, not character) persona of him being a risky pilot - mouthing off to superiors when he knows he's right, etc. more of a true WWII pilot type; ballsy and seemingly a bit crazy. much more unique characterization within the DCU, and one i can see reynolds pulling off.
more importantly, i think he's a good-enough actor and he resembles hal, and that's really all i need to know at this point to make this sound like a good fit. from this point on, it has little to do with reynolds and more to do with the story and aura of the film (lighthearted, sci-fi, dark, etc) that will determine how it plays out.
