There was a movie about a trip to the moon that I saw as a kid on TV, which gave me nightmares. I don’t recall the name but it wasn’t this one. I suppose it was similar to the low-budget, objectively terrible horror films from the 50’s. When the crew got to the moon they had been told to not venture out in direct sunlight because they could roast to death, so they had to stay in the shadows. There were also creatures on the moon who were sort of giant rock monsters. (Maybe Harryhausen was involved in that.) Naturally these two plot elements worked together.
