If you’re among the millions of Americans who’ve seen Gravity, you probably remember one of the movie’s quietest but most powerful moments: the conversation that Sandra Bullock has with an unknown and unpictured Inuit man, as she calls for help and ends up coming to terms with her own mortality.

While director Alfonso Cuarón and co-screenwriter Jonás Cuarón (who is also Alfonso’s son) were putting together Gravity, they decided to have Jonás shoot this companion film that shows the other side of that conversation. The audio was made to be synchronized seamlessly across each film, but as Jonás says, he wanted to make sure it was “a piece that could stand on its own.” Now, via the Hollywood Reporter, you can watch that short film in its entirety in the player below.

While the short is largely about the distance between Aningaaq, the title character, and Bullock’s Dr. Ryan Stone, thematically the two companion films are on the same wavelength: Both are about characters trying to survive in cold, harsh environments, and learning to let go. The Bullock half of this scene is also among the bleakest in the movie, and this short is no less dark. (Dog-lovers should know it contains some difficult material.) But, as with Gravity, the cinematography is also gorgeous, which helps make the struggles easier to bear.

We’ll see whether the short has any luck with the Academy—Warner Bros. has decided to submit it for Best Live Action Short—but in the meantime it’s worth watching for any fans who can’t wait to revisit the groundbreaking film.
