Jonas Cuarón's Gravity spinoff short film has been unveiled, Digital Spy said.

The short film, titled Aningaaq, offers viewers the chance to learn more about the male voice Sandra Bullock's Ryan makes contact with via radio in the blockbuster.

Jonas, the son of Gravity director Alfonso Cuarón, co-wrote the screenplay for the Sandra Bullock space epic with his father.

The spinoff follows an Inuit fisherman stationed on a remote fjord in Greenland as he picks up Bullock's voice on the radio.

"It's this moment where the audience and the character get this hope that Ryan is finally going to be okay," Jonas Cuarón, 31, tells The Hollywood Reporter. "Then you realise that everything gets lost in translation."

Aningaaq was originally intended as a bonus feature for the DVD and Blu-ray release of Gravity, but will now be submitted for Oscar consideration following a number of festival screenings.

It will be submitted for the live-action short category, while Gravity is expected to receive multiple nominations from the Academy.

If they are both nominated, they will make history as the first feature and spinoff short drawn from the same material to be nominated together in the same year.
