Here's a name who's occurred to me recently. German-Irish actor Michael Fassbender, who played Stelios in 300 and has been cast as a Nazi villain in Tarantino's forthcoming Inglorious Bastards (the role for which Leo DiCaprio was initially in the running). He is currently getting rave reviews for playing hunger striker Bobby Sands in Hunger, for which he slimmed down to Christian-Bale-in-The-Machinist type proportions. In fact, he is somewhat like Bale, IMHO, and would probably bulk up like Bale did for Batman if cast as a superhero. He's 6'0", too short for some of you, I know, but surely better a decent actor like that than some plank of WWF wood?
And hey, with an Irish director (apparently) making the movie ...
Sadly no pic of him on his imdb page, but it shouldn't be too hard for the curious of you to find a link.
