The crowning achievement of Robin Williams’ storied career is not the Mork and Mindy sitcom where he was first discovered. It’s not the numerous leading roles he has received recognition with, such as Best Lead Actor Academy Awards (Good Morning, Vietnam, The Fisher King, Dead Poets Society). It was not in the numerous timeless comedies we’ll watch for ages (Mrs. Doubtfire, The Birdcage, Jack, Robots, Night at the Smithsonian, Jumanji). It’s not for his creepingly effective turns in movies like Insomnia, One Hour Photo, The Night Listener, or heartwarming dramas such as Awakenings. Heck, it was not as the voice of The Genie in Aladdin. Instead, it is a community college professor who has not been able to move on from his life after losing his wife to cancer in Gus Van Sant’s (Milk, Drugstore Cowboy) surprise 1997 hit Good Will Hunting. Nevertheless, the film earned Williams the only Oscar of his career. And he’s not even the best part of this movie.
