Topher Grace rose to fame by playing Eric Forman on That 70s Show, but surprised fans when he left the show after its seventh season. Rumors circulated that there was behind-the-scenes drama, but Grace denied these claims. His co-stars spoke highly of him, except for Laura Prepon, who criticized his kissing skills. However, Joseph Gordon-Levitt defended Grace, saying he was a good kisser. It was also revealed that Grace and Prepon never dated during their time on the show.
