Say what you want about Eric Bana, but you can't deny that some of his roles are really badaas. Hector, Nero, Avner, and my favorite Hoot, were really cool characters. He is Australian with Croatian heritage and just a cool guy. He was born in Melbourne and is one of those Australian badasses. I personally think he is a good actor.
