You should learn to be happy with what you have. Besides, the fact that I'm not a huge star has allowed me to pick and choose the roles I want to do, not the ones some person sitting in a studio office thinks I should do.
I'm not particularly a career-oriented guy. I'm lucky. I can make really interesting films much of the time with interesting people yet be anonymous, have a private life. But, I'd like to have the choice of the better roles.
