Director Alfonso Cuarón discusses why the immersive IMAX format is perfect for Gravity in a behind-the-scenes featurette, revealing that he was inspired by the 2010 IMAX documentary Hubble 3D while designing the film. We also hear from actual NASA astronauts who consulted on the sci-fi thriller in this four-minute presentation. In addition, Warner Bros. has released the sixth TV spot for this October 4 release.

Dr. Ryan Stone (Sandra Bullock) is a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalsky (George 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.
