I caught an early screening a couple of days ago. It's majestic and insanely intense: no quiet existentialist film here, it's far closer to a straight-up action movie (albeit with art-house tendencies). I pretty much guarantee you've never seen (or heard) anything like it -- it's an absolute cinema experience for the ages. See it on the biggest possible screen, in 3-D (yes! you read that right) with a huge sound-system.
(If you aren't familiar with it, it stars Sandra Bullock and George Clooney as two astronauts who're trapped in orbit after their shuttle suffers a disaster. The story is extremely simple: will they live and find a way to get back to Earth before they run out of oxygen, propellant, and/or have their life-support systems ruined by some of the deadly shrapnel that's flying about?)
Here's the trailer:
