As the title suggest name a show where damn-near the entire cast's career is nonexistent or where you thought it would be.

Obviously, just because a person was an actor doesn't mean they want to be one for the rest of their life. I'm talking about the ones that seemed to want to be A++ celebrity but haven't be successful.

Often having a successful role on a hit TV show doesn't equate career success because the person is often forever associated as that character. If you start your acting career or got your big break playing in a hit TV series you'll always be remembered as that character. So it's really hard to get cast in other roles and have an amazing career afterwards.
