I can do comedy so people want me to do that but the other side of comedy is depression. Deep deep depression is the flip side of comedy. Casting agents don't realize it but in order to be funny you have to have that other side.
You need some insecurity if you're an actor. It keeps the pot boiling. I haven't yet started to think about retiring. I was shocked when I heard about Paul Newman retiring at age 82. Most actors just fade away like old soldiers.
