Question:

Where can i find good acting companies in the LA area?

I would really like to be extras in movies and audition for commercials but i cant find any good companies.I live in the LA area and have being looking for some sort of acting company, do you know of any good ones?

Best Answer - Chosen by Asker: Seriously?

Pick up a newspaper, or a Variety. Do you really live in LA? Because that seems like kind of a silly question to me.
