Guy Gardner or John Constantine?

Since I somehow doubt he'll be back in the X-Men universe, maybe he could do a DC movie. If he can do a decent American accent, he'd make an excellent Guy. He looks good with a crew cut and he has the attitude. Besides, it would be kind of ironic if he starred in a good Green Lantern after Reynolds helped sink the last one. Otherwise, maybe he'd make a good, if somewhat young, John Constantine.
