George Clooney
We know George Clooney is very successful in the entertainment industry. He won three Golden Globe Awards and two Academy Awards. However, Clooney portrayed Dr. Doug Ross in ER for five years before movies started calling his name. His bad-boy character moved to Seattle. He made a secret appearance in season six when he helped Julianna Margulies leave the show. Both returned for an episode in the final season.
