It's important to keep challenging myself and try to come up with some new face every now and again.
I've played English a number of times, and used an English accent a number of times, so it becomes a little bit of an obstacle course to go, "Oh, that's teetering into Captain Jack-ville," or "This is teetering into Chocolat or Wonka." You've got to really pay attention to the places you've been. But, that's part of it. That's the great challenge. You may get it wrong. There's a very good possibility that you can fall flat on your face, but that's a healthy thing for an actor.
The challenge for me is still to do something that hasn't been beaten into the movie going consciousness. Otherwise what am I in it for?
