George Clooney got his start on the NBC show "ER" as Dr. Doug Ross, pictured left. Since then, Clooney, pictured right at the "Burn After Reading" premiere at the Venice Film Festival, has been voted one of People magazine's Most Beautiful People, and has gone on to star in such Hollywood blockbuster hits as "Michael Clayton" and "Ocean's Twelve." Viewed as an international sex symbol, Clooney was the second man to appear on Vogue's cover, after Richard Gere.

On January 21, People magazine reported that Clooney's character Dr. Ross will return to the show in its final season. Sources told E! News that Clooney has already shot an upcoming episode of the show -- including scenes with actress Susan Sarandon, who will appear on the show, according to E! News.
