Alfonso Quaron's "Gravity" is confirmed to have its world premiere at this year's Venice Film Festival. The space-set movie, in which George Clooney and Sandra Bullock star as two astronauts stranded in space after their craft gets hit by flying debris, will screen out of competition on August 28 in the Sala Grande of the Palazzo del Cinema at the Lido.

This marks the first time a Quaron film will be up at the festival without getting in the competition. His previous directing gigs "Y Tu Mama Tambien", co-written by his brother Carlos, and "Children of Men", which starred Clive Owen and Julianne Moore, won awards when they played at the festival.

"Gravity" will be the first 3D movie that is set to open the Venice event, the world's oldest film festival. The last time it opened with a sci-fi film was in 2000, with Clint Eastwood-directed "Space Cowboys" at the 57th Film Festival.

The 70th Venice International Film Festival runs August 28 - September 27. Chaired by Paolo Baratta, the event is organized by the Biennale di Venezia and directed by Alberto Barbera, who also took charge of the 2001 festival where Quaron's "Y Tu Mama Tambien" won the Golden Osella award for best Screenplay.

"Gravity" is set for an October 4 wide release in the U.S.
