A Scout is never taken by surprise; he knows exactly what to do when anything unexpected happens.
I think people need to have fun with whatever they're doing - makeup, their clothes, music, live shows - anything you don't need to take too seriously, don't take too seriously.
When actors get pigeonholed, that's their own doing to a large degree. Because if you do something that people like, obviously they're going to ask you to do it again. It's up to you to say no. If you're that insecure about working, you'll probably do what you're known to do.
