A new IMAX featurette for director Alfonso Cuaron’s space-set dramatic thriller Gravity has been released online.  In this new behind-the-scenes look at the film, we see Cuaron discuss using the immersive IMAX format to bring his story to the screen, and we also see a few astronauts talk about the accuracy with which Cuaron depicted space.  The filmmaker says his greatest influence on Gravity was the Hubble 3D IMAX documentary, and indeed the images captured in the film really feel like you’re there floating in space alongside Sandra Bullock’s Dr. Ryan Stone.

Here’s the official synopsis for Gravity:

GRAVITY, directed by Oscar® nominee Alfonso Cuaron, stars Oscar® winners Sandra Bullock and George Clooney in a heart-pounding thriller that pulls you into the infinite and unforgiving realm of deep space. Bullock plays Dr. Ryan Stone, a brilliant medical engineer on her first shuttle mission with veteran astronaut Matt Kowalsky (Clooney). But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalsky completely alone—tethered to nothing but each other and spiraling out into the blackness. The deafening silence tells them they have lost any link to Earth… and any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go further out into the terrifying expanse of space.
