Soap Opera Actress vs. _____ Actress

I was checking up on the latest TV entertainment news on tvweek.com and notice that Sarah Brown is leaving General Hospital. It was a big mistake when she left the first time when she was playing the role of Carly... that's when I was down with General Hospital and never missed an episode. But anyway... the point of this blog is... I've noticed that a lot of soap opera actors and actress don't play huge Hollywood roles. Why? Is it because their not accepted or absolutely, positively, don't want any parts? A lot of them, not all, are really good at what they do. I would love to see Maurice Benard and Steve Burton in a main stream hollywood film.
