Alright, you've seen Real Space. Now, for Fake Space. Gravity is only director Alfonso Cuaron's fourth movie released in the last 12 years—he previously did the insanely good Children of Men and the best Harry Potter, Prisoner of Azkaban, so the method pays off for him. The film stars George Clooney and Sandra Bullock and, from the looks of the trailer, it might be a must-see while stoned-in-IMAX 3-D come October 4.
Keep in mind that the entire 90 seconds is one long special-effects shot, and it's all totally seamless, down to Bullock's overacting. (Gravity, by the way, reportedly features one take for the first 20 minutes, which is a long, long time for a camera to swoop around.)
