Corrected entry: Barrow, Alaska is north of the Arctic Circle. As such, at the time of the year (October) that the movie is set in, there would be no daylight (it would be nighttime 24/7). Yet there are many scenes that take place in the daylight.

Correction: Barrow is not dark 24/7 in October. That occurs in December. Even at the end of October, Barrow gets 6 hours of daylight.
