Biografia

His American accent, when auditioning for Batman Begins (2005), was so convincing that the casting directors had no clue he was really from Ireland.

Is the only actor playing a villain to appear in all three of Christopher Nolan's Batman films.

An intensely private person, he prefers not to speak about his personal life and did not appear on any live TV chat shows until 2010.

He was planning a career in law until he discovered the world of acting.

His first name is pronounced "Kill-ian".

I'd probably have been wealthier if I had stayed with law, but pretty miserable doing it.

It's basically lazy journalism if they say I'm the new Colin Farrell. This thing about heat, it's all just hot air.

[on breaking the Irish typecast] You're an actor who's Irish, not an Irish actor. And you shouldn't be limited by your extraction.

[on auditioning for Batman Begins (2005)] Well, the first part of the question, I think if you ask any male if you really want to get into a real suit, that was a dream come true, obviously, and then just to get to work with Chris, even for that little test, was amazing as well; and then, I don't know, he saw something in it that he thought maybe he could use for the other characters.

[on accepting the role of the Scarecrow in Batman Begins (2005)] I can have a bit of fun with it, too, because my only motivation really is being bad. I love doing proper dramatic character studies, but it's also good to have a bit of fun, dress up and stuff.
