For five seasons, George Clooney played heartthrob and pediatric surgeon Dr. Doug Ross on ER. His role as the charming, womanizing bad-boy was met with almost overnight success, with the show becoming television’s most-watched drama and cementing the actor, who was relatively unknown at the time, as a household name. Ross’s occasionally explosive exploits at the County General Hospital in Chicago and his will-they-won’t they relationship with Nurse Carol Hathaway (Julianna Margulies) were highlights in early seasons, and Ross became one of the breakout characters of the show.
However, in the 16th episode of ER‘s fifth season, Ross departed the series. Let’s look at who Dr. Ross was on ER and why George Clooney left the show.
