Cinematic mastermind Stanley Kubrick consistently churned out four-star films. General audiences may best remember him for The Shining, or maybe 2001: A Space Odyssey, or perhaps A Clockwork Orange, or possibly... You get the idea.
You'd be hard-pressed to find someone who doesn't consider Kubrick to be one of the greatest American directors ever. Well, except for the AMPAS. Sure, he received a Best Visual Effects award as part of the team behind 2001, but Kubrick's a director, dammit, and one of the all-time best. One who unbelievably never won the Best Director honor.
