A wooly mammoth that came back to life because they thawed it out? Sorry, got nothing for you.
Hey, just thinking of obscure movies that stuck with me – Horror at 37,000 Feet. It’s a tv movie about “an invisible demon in the cargo hold of a jet airliner [that] terrorizes the passengers.” The demon suspends the plane in a headwind so it’s stuck in place and in horror movie fashion, picks them off one by one as I recall. Does anyone remember this one? I remember it because it had William Shatner as a Priest who abandoned his faith but when he realizes there’s a demon, that means there’s also a god.
I didn’t remember the rest of the cast but IMDB says it also has Buddy Ebsen, Chuck Connors, Roy Thinnes (Invaders) and Paul Winfield. A typical disaster movie cast of B actors, though Ebsen and Shatner would see their careers upswing, and Winfield had a good Hollywood movie career ahead. It was probably near the end for Connors and Thinnes, though. It also had Russell Johnson, the Professor from Gilligan’s Island.
