Speaking as Hollywood "insider", I hate to break it to you but most movie stars are bossy and self-centered and virtually oblivious to anything and everything but themselves.

Sharon Stone is actually -- believe it or not -- better than most, because most of the time she is civil, meaning she doesn't scream obscenities or hurl objects at anyone daring to question him/her. She also isn't petty. I know stars that would have had (or try to have) your friend fired.

This is not news, and not America-centric. My limited experience with Hispanic Stars would indicate they're just the same.

There are exceptions, I could name a few, but not that many.
