Sandra Bullock and George Clooney in 'Gravity'Warner Bros.


They say that in space, no one can hear you scream. At least in Alfonso Cuaron's upcoming film "Gravity," Dr. Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) can hear each other.

This teaser gives us a terrifying taste of what's in store for Stone, a medical engineer and space newbie, and Kowalsky after their ship is struck and destroyed by debris. The only things they have left are their space suits, a dwindling supply of oxygen, and their partnership.

The first trailer for the movie came out in May, and it was scary, but not quite as stark as this one. Here we glimpse Stone and Kowalsky's growing panic as the debris hits and Stone struggles to detach from the shuttle. If you can watch this without your palms getting sweaty, well, congrats on your nerves of steel.

"Gravity" will premiere at the Toronto Film Festival in September. It opens on October 4 in IMAX and IMAX 3D.
