George Clooney's 'E.R.' Sequel Doesn't Go as Planned (Video)

George Clooney looks confused while back in costume during an E.R. themed skit on Jimmy Kimmel Live on Tuesday (February 2) in Hollywood.

The 54-year-old actor, who is promoting his new movie Hail, Caesar, thought he was going to be having a reunion for his old NBC series, but he was then informed that his former co-stars couldn’t attend.

Jimmy said that Julianna Margulies was busy filming The Good Wife, Noah Wyle had Taco Tuesday plans, and Eriq La Salle had jury duty. One person who did show up, though he wasn’t on E.R. at the same time as George, was Hugh Laurie!
