I watched The Beast from 20,000 Fathoms (1953), a 1953 Warner Brothers film based on the short story, The Fog, by Ray Bradbury (Fahrenheit 451, The Martian Chronicles, The Illustrated Man) on Svengoolie. This a Ray Harryhausen stop-motion creature, the fictional Rhedosaurus, inspired by King Kong, the head of a T-Rex, the body of an Iguana and crocodile features. In the movie it appears to be 200 feet long but the model was actually only 30 inches.
20,000 fathoms is 22.73 miles in case you were wondering. The Arctic scenes were filmed at Hollywood studios on the hottest day of that year using snow machines. The avalanche, near the opening, was actually borrowed from the 1935 movie She.
They used glycerin on the monster model when they wanted it to look wet and the stop-motion scenes took 6-7 months to film. The growls of the Rhedosaurus were actually those of a large cat.
