I thought the guy she was talking to might be Mongolian but googling the name (Aningaaq) turns up this short that Jonas Cuaron filmed separately as a companion piece to Gravity. It tells the story of an Inuit fisherman, so the guy could've been anywhere in Canada, Alaska, Greenland or Siberia

Loved that scene, I thought it added a lot to Bullock's character
