It's the ultimate nightmare space exploration scenario: a routine space walk turns into chaos when satellite debris crashes into the space shuttle.
In this clip from upcoming Warner Bros. film "Gravity," that's just what happens and Dr. Ryan Stone (Sandra Bullock) is catapulted into space. As she spins farther into the void, astronaut Matt Kowalsky (George Clooney) radios, "Houston, I've lost visual of Dr. Stone."
Director Alfonzo Cuarón released this stunning teaser at the annual Comic-Con convention last week in San Diego. The film is scheduled to hit theaters Oct. 4.
