WARNING: If you haven't seen the first completely amazing trailer for Alfonso Cuaron's Gravity, do so now. This new trailer, titled "Drifting," is clearly a sequel to the first trailer, and while it's pretty gripping, it's so much more effective if you watch the original trailer first.

Did you watch them both? Holy hell. I thought the first trailer was scary enough, but watching Sandra Bullock flip through space, completely alone, was so terrifying it actually made me a little nauseous. I can't wait to see — and probably be completely traumatized by — Gravity when it comes out on October 4th.
