Barry Corbin: I love doing pilots, but frankly, I'm not that crazy about signing up for series work. What usually happens is that the series ends up repeating what you did in the pilot. That's not only boring but it's artistic suicide. You do the same character over and over again and the perception becomes that's all you can do. Before long, the perception becomes truth. That's all you can do. To prevent that, you'd better be very careful about what seven-year contracts you sign.
