At the beginning of the film, after the object (thought to be a meteor) has landed, there is an extreme close-up of a typewriter as a report is being typed out. What is actually typed out is "metor lands."
The English title "Terror in the Midnight Sun" isn't logical. Since it's set in the Swedish winter, the midnight sun is something that occurs in northernmost Sweden during the summer. The same areas in the winter are almost all-day dark.
