There are always good parts. They may not pay what you want, and they may not have as many days' work as you want, they may not have the billing that you want, they may not have a lot of things, but - the content of the role itself - I find there are many roles.
You have actors who begin at a certain young age and there's very little change in their technique and the depth of their performances; they're the same 30 years later.
