George Clooney made his feature debut in 1983’s Grizzly 2: The Revenge, but the film didn’t get a proper release until 2020. Did he wait around for Grizzly 2 to provide his big break? He did not. He scored his breakthrough role on ER, proved his movie stardom in Out of Sight, went on to anchor the Ocean’s movies, and earned his first Oscar — for Best Supporting Actor — in 2005’s Syriana.
He kept turning in excellent performances in films like Michael Clayton while directing films like the excellent Good Night and Good Luck (his 2005 directorial debut.) And he picked up another Oscar as one of the producer of Ben Affleck’s Argo.
