A teaser trailer for Gravity, the new movie from Alfonso Cuarón, has rolled out online. The sci-fi movie follows two astronauts played by Sandra Bullock and George Clooney who get stranded on a damaged space station with absolutely no communications with Earth. Spanish filmmaker Cuarón is best known for his dystopian future Earth flick Children of Men - with Clive Owen - though Gravity appears to be vastly different ground.

The teaser trailer focuses on the devastating accident that leaves the astronauts set adrift from their ship. The visuals are stunning and Cuarón appears to be the right man to take the colors and stark atmosphere in space and present it on the big-screen. The most important thing about Gravity is that it looks very different from the slew of sci-fi movies coming out this year - After Earth, Star Trek etc - and that's definitely no bad thing.  

Gravity - written by Cuarón and his son Jonás - was originally developed by Universal, before Warner Bros took over. The studio approached multiple actresses before casting Bullock, while Robert Downey Jr was also involved as the male lead before leaving the project and being replaced by Clooney.

'Gravity' will hit theaters on October 4, 2013.
