Sometimes you just work, you work, you work, and you have no life, no boyfriend, you have no more friends, no more nothing, you just make movies, and you're tired, and you don't know why. Then everybody says, 'Oh you are so lucky, you are working!' And you're like, 'Oh yeah, oh yeah, it's so great!'
There is that stereotype of a nerd with the high pants and pocket protector and that kind of thing. That can sustain comedy for maybe a movie - hence the 'Revenge of the Nerds' franchise - but not for hopefully years on the air. It's a sight gag, not a story.
Actors, lots of times, are great when they have great parts. For me, a lot of times, it's been the part.
