King Kong 1967

King Kong is a giant ape, the last member of his species (Megaprimatus Kong). They are not native to Skull Island, but it is presumed that the species Gigantopithecus, a prehistoric gorilla that was bigger than modern apes, came to the island via an ancient land bridge linked to Asia. This of course happened many thousands of years ago.

King Kong Escapes (1967). Another Toho film in which Kong faces both a mechanical double, dubbed Mechani-Kong, and a giant theropod dinosaur known as Gorosaurus (who would appear in Toho's Destroy All Monsters the next year). This movie was influenced by the contemporaneous cartoon television program, as indicated by the use of its recurring villain, Dr. Who, in the same capacity.
