Ah, CREATURE FROM THE HAUNTED SEA (1961) is an aweful film. I remember watching this one. The jazzy music drove me crazy and the monster had ping pong type eyeballs. I had some kind of Roger Corman Creature DVD Features back a while ago and I think it had four of his films on it. One of the other films was BEAST FROM HAUNTED CAVE (1959) directed by Monte Hellman under Roger Corman. Well, I guess we just had to see them. : )
BEAST FROM HAUNTED CAVE (1959) is shot at some kind of ski resort and cave. I was wondering if it was shot along with SKI TROOP ATTACK (1960), but found out it was made a year later, but I bet they were made the same week.
