Being one who likes fantastical literature, I find this funny:

Bill Nighy, some British actor, plays a range of characters that I only just now noticed. He is a sleazy politician with no soul in The Constant Gardener, a master vampire in the Underworld movies, a loser musician in Love Actually, among others. The juxtaposition of His Lord King Master Allmighty High Vampire with Billy Idol-in-his-downfall musician is especially amusing.

Perhaps I am the only one that finds this entertaining, but it's just too surprising to watch a movie in which you are deeply involved (The Constant Gardener), then think "Hey, I've seen this guy before." then realize the last time you saw him was with blood smeared on his chin, and his eyes all vampire-weird. You don't immediately register him as as an actor.
