You look at William Powell in My Man Godfrey and he's a butler in that and he's very dapper. He's a very refined gentleman. I liked playing around with that, with the good posture and a style, a panache, and a way of moving about the room.
I like to imagine, if I was in the 1930s and was rich and a psychopathic killer, I probably would be moving about very freely and having a lot of fun.
I always at home as a kid tried to move something with your hand and it doesn't move and then you get to do it in a movie. I mean my superpower is quickness but you know what I'm saying. You get a superpower and you're like "Man this is awesome. I get to pretend I have a superpower."
