Troy star Eric Bana embraces darker roles because he wants to experience the intense feelings his characters have.
The actor has had a variety of intense roles in films including CHOPPER, MUNICH and Black Hawk Down.
He tells Elle magazine, "I have a problem where, when I think I'm looking friendly, I look like I want to kill someone.
"If my character has to feel something, I pretty much want to feel it. I want to feel like I'm killing someone. I want to feel the guilt someone feels after he's stabbed someone or shot someone.
"I want to feel the fear of pointing a gun at someone. Because it's just bloody interesting. Otherwise it just feels fake."
