Gravity hits theaters in 3D, 2D & IMAX 3D this October 4th, Dr. Ryan Stone [Sandra Bullock] is a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalsky [George Clooney] in command of his last flight before retiring. But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone & Kowalsky completely alone--tethered to nothing but each other & spiralling out into the blackness. The deafening silence tells them they have lost any link to Earth...& any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left.
