Latest, Greatest 'Gravity' Trailer

There have been a few terrifying trailers that feature Sandra Bullock spinning helplessly in space, but now, Warner Bros. has released the first official trailer for Gravity and it features Sandra Bullock, spinning helplessly in space. But! There's other stuff too, like George Clooney's voice, visuals inside the space shuttle, and a few lines that clue us into the fact that Bullock's character has a brown-haired daughter at home in Illinois.

Nevertheless, the trailer is surprisingly compelling.

Before Bullock got the part in Gravity, Blake Lively and Scarlett Johansson vied for the role of medical engineer Dr. Ryan Stone. Bullock was obviously a wise decision — it would've been very difficult to believe 26-year-old Lively was a PhD astronaut with nerves of steel. Before Clooney, Robert Downey Jr. was also attached to the film.

The movie is directed by Alfonso Curaón, whose IMDb profile, for the record, says he always wanted to be an astronaut. Curaón is known for Children of Men and Y Tu Mamá También and also co-wrote, co-produced, and co-edited Gravity, which is expected to hit theaters on Oct. 4, 2013.

The movie will have its North American premiere at the Toronto Film Festival this week, but made its world debut at the Venice Film Festival in August, where it received rave reviews — it's been called "nerve-shredding" and "extraordinary."
