Snubbed for: Best Picture
Lost to: How Green Was My Valley
Year: 1942

Leave it up to the Academy to brick properly awarding what would go on to be considered the best film of all time. What the hell is a How Green Was My Valley, even? OK, it's actually a pretty good John Ford flick, worthy of ending up on any self-respecting film buff's must-watch queue. But has it been taught in film courses across the country for the past several decades? And there endeth the debate.
