<p>I agree with what has already been said. As long as you are comfortable in auditions, I can’t see that it would in any way affect your “castability”. One of my favorite local actors is absolutely fantastic on stage and will take on any role, no matter how outlandish. Off stage, he is a very unassuming and quiet person, and a bit shy. He told me that the hardest thing for him to do is to get up in front of a group for a speech, such as in a speech class, or in a business meeting. However, put him on a stage as an actor and he is wonderful and natural. He says that when he is acting, he feels totally free to let go. I have read this about several more well known actors, so it sounds like you are in good company!</p>
