Jackie Gleason was the ultimate comedic genius. One of the earliest superstars of television, Gleason's 1950s variety show became one of the first "must-see TV" series. His 39 episode spin-off of his sketches based on The Honeymooners remains arguably the funniest sitcom ever created. Yet, many people forget The Great One's film career. He could be a consummate dramatic actor - and if you doubt it, just watch his brief performance in The Hustler which earned him an Oscar nomination despite being onscreen for about ten minutes. Also check out his heartbreaking, Willy Lohman-like character in his final film Nothing in Common opposite Tom Hanks.
