Mariel Hemingway: I enjoy making things that are different. It makes for a better career. I don't want to do the same thing twice. I love the different roles I've played. I don't ever want to be pigeonholed! That's the great thing about acting -- all these different people I can play, as long as audiences are willing to see them. The more different roles I do, the more different roles I will get.
