The canister is bought by a zoologist from a young boy who finds it and soon the creature hatches and begins to grow at a frightening rate. Hopper is the only surviving astronaut from the trip and he an the US Military try and find the monster. they race around Italy and soon find the creature and trap him alive.
It escapes again and destroys a lot of Rome before finally being destroyed. The Ymir is a master work of Ray Harryhausen. This is a fun film and one that needs to be re-watched every now and then. Hopper and Taylor are fine in the lead roles an the entire film rolls along very smoothly.
