This video has been around since 2009, so maybe you've already seen it — but it's a pretty great, thought-provoking discussion nonetheless. Terry Gilliam, interviewed by TCM, explains the major difference between movies like Stanley Kubrick's 2001: A Space Odyssey and the mega-successful but more comforting works by Steven Spielberg. Even if you don't agree with Gilliam, it's still pretty thought-provoking stuff. [via Javier Grillo-Marxuach on Twitter]
