Car troubles are the worst, right? WRONG. Space station troubles are the worst, as Sandra Bullock and George Clooney will now demonstrate in the trailer for Gravity, Alfonso Cuarón's first film since 2006's very amazing Children of Men. It's been three years since we heard Gravity will open with an uninterrupted twenty-minute-long take, and it looks like bits of this trailer come from that future Best Cinematography Oscar-winning work. "Gorgeous" doesn't cut it — this might be the most "you HAVE to watch this at high resolution in full screen" trailer ever. The film opens on Oct. 4.
