When you get all this stuff on and you put on the guns and the hair, it has an effect on the actor. It tends to lend a certain something to the way you feel as you're just walking around looking that way.
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.
