Colin was plucked from obscurity (read: Ireland) when Joel cast him in 2000's Tigerland. But to hear the director tell it, the choice was made for him. "We were casting Tigerland and I happened to be in London meetings with all these guys because there are so many parts in Tigerland. We'd read 44 actors in three days, but Colin walked in, we didn't even make him read. The search was over."
