Alfonso Cuaron's latest Gravity trailer will knock the wind right out of you. The simple two-minute clip — made entirely in one take — shows what happens when things fall apart for George Clooney and Sandra Bullock in space. It is simply stunning.

Earlier this year The Film Stage revealed that Gravity only has 156 shots in its two-hour runtime. Including the opening scene which will be an unbroken 17-minute shot. Which is exactly what you're getting a sneak peek of right now.

GRAVITY, directed by Oscar® nominee Alfonso Cuaron, stars Oscar® winners Sandra Bullock and George Clooney in a heart-pounding thriller that pulls you into the infinite and unforgiving realm of deep space. Bullock plays Dr. Ryan Stone, a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalsky (Clooney). But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalsky completely alone—tethered to nothing but each other and spiraling out into the blackness. The deafening silence tells them they have lost any link to Earth…and any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go further out into the terrifying expanse of space.

Gravity will premiere at TIFF and later open on October 4th.
