Topher Grace
Topher Grace is best known for playing Eric Foreman on That '70s Show, but his reputation certainly precedes him. After abruptly leaving the show before it was finished, the actor's co-stars called him rude and arrogant. Surprisingly, their words made an impact. Over the years, Grace has tried to turn things around, and he's slowly succeeding. These days, fans call him "a stand-up guy" and his co-stars only have nice things to say about him. Other celebs should learn from his behavior!
