IMAX has released a Gravity behind-the-scenes featurette, Digital Spy said.

The 'Behind the Frame' video sees director Alfonso Cuarón discussing his approach to making the recreation of outer space seem as realistic as possible.

In justifying his use of 3D, Cuarón explains that he wanted the film - starring Sandra Bullock and George Clooney as astronauts stranded in space after their space shuttle is damaged - to be completely immersive for the audience.

"A lot of films nowadays... you can watch with your eyes closed; everything is being told to you," he said.

"Gravity is a film about the experience of seeing and hearing."

As well as revealing techniques used to make the setting recognisable for cinema-goers, the video also explores astronauts who were consulted on the realities of life on a space station, and the physics that applies when outside the Earth's atmosphere.

“At once the most realistic and beautifully choreographed film ever set in space, Gravity is a thrillingly realized survival story spiked with interludes of breath-catching tension and startling surprise.

Not at all a science fiction film in the conventional sense, Alfonso Cuaron's first feature in seven years has no aliens, space ship battles or dystopian societies, just the intimate spectacle of a man and a woman trying to cope in the most hostile possible environment across a very tight 90 minutes.

World premiered at the Venice Film Festival, with Telluride showings following quickly on its heels, this Warner Bros. release is smart but not arty, dramatically straightforward but so dazzlingly told as to make it a benchmark in its field. Graced by exemplary 3D work and bound to look great in Imax, the film seems set to soar commercially around the world,” a review published at The Hollywood Reporter said.

Gravity is released in 3D and IMAX 3D on October 4 in the U.S., and opens on November 8 in the UK.
