Corrected entry: The towns of Nightmute and Unkumiut are not inside the Arctic circle. They actually experience darkness all year around, but the movie said the sun never sets.
Corrected entry: At the end of the movie, in the beach house, Dormer leaves the house and falls down in front of it. Then Ellie comes from the other house with a blanket to cover him. The question is, why did she bring a blanket, if she didn't know that Dormer was shot?
