Terror in the Midnight Sun (1959)
Mom loves this film and she'd love to see it riffed!
From IMDB -
"Aliens release a furry critter in the wilds of Lapland where it takes a woman captive and threatens a group of scientists."
Well, they kinda did this with Invasion of the Animal People, but I'd be up for a fresh riff of the real movie before Jerry Warren got to it.
