When someone you have a lot of respect for believes in you it helps you believe in yourself.
I actually have more respect for people who are in the closet. You end up exposing so much of yourself because you have to talk about your sexual life. You shouldn't have to talk about it.
The worst thing that an actor can do is go into any project with a lack of respect for the material. You can have an opinion about it but you have to respect yourself in doing it.
