Take a deep breath -- you'll need it.
The official trailer for Gravity is the longest and most unnerving look at Alfonso Cuarón's space thriller, starring Academy Award-winners Sandra Bullock and George Clooney.
Previous trailers gave audiences a peek at Bullock's character, Dr. Ryan Stone, helplessly tumbling through the dark voids of space. The new trailer builds upon the action, using Stone's desperate breaths to echo throughout the footage.
The trailer also adds emotional depth to the plot. Clooney's character Matt Kowalsky asks Stone, "Is there somebody down there looking up, thinking about you?”
"I had a daughter. A little girl with brown hair. Tell her that I’m not quitting," Stone responds.
The film arrives in theaters on Oct. 4.
