The Beast From 20,000 Fathoms (1953 film)

''The Beast from 20,000 Fathoms is an American science-fiction film, directed by Eugene Lourie and released in 1953. The movie features a fictional species of dinosaur, Rhedosaurus, which thaws out of the ice due to an Arctic nuclear test and makes its way down the coastline of the U.S., eventually ending up in New York, where it is slain by the military. In the film, the creature has an ancient disease which had lain dormant along with it in the ice, but has now taken effect again once it was thawed, causing sores all over the creature's body. One of these sores is used by the army to fire a shell into, which eventually kills it.
