Damian Lewis is incredible on the TV show Homeland, although I first started digging on him when he was on the now-defunct show called Life. He was brilliant.
I once thought I saw Damian in the audience at Sundance and called out to him. When the guy came over, he said, "Who do you think I am?" I said, "The guy from Life." NOPE. Fail. Luckily, the real Damian is very fan-friendly. Yay.
