4. Justin Bartha
Another fairly off-the-wall addition, Bartha has the same appeal as Morrison in that I believe he could play Barry Allen just as well as the Flash. Despite fairly big roles in the
National Treasure movies and
The Hangover films, Bartha's really yet to burst out onto the scene as a leading man. I'd like to see him appear as Allen in a
Justice League film, and then go see him take a franchise on his own (regarding he plays the part well the first time). Likable, fun, and
real, Bartha comes off to me as the perfect character who's always late for everything and spends his evenings speed-reading when he should be realizing he's late for another date with Iris West. I'm rooting for you, Bartha, that you get a big break fairly soon.
