“Twenty Million Miles to Earth”, 1957
Ray Harryhausen’s original design for the monster was a giant cyclops, similar to the one he later used in the 1958 “The 7th Voyage of Sinbad”. He discarded the idea after making a clay model of it, and eventually settled on the reptilian Ymir. The Ymir roars in the film are variations of elephant roars sped up and modulated in pitches at different rates.
Since he planned to use a real elephant for some of the footage in the zoo, Ray Harryhausen asked for one that was 15 feet tall, but the film studio was only able to procure an eight-foot-tall one for him. In order to make the elephant look much bigger, a 4’6″ actor was cast to play the zookeeper.
