20 Million Miles To Earth (1957)
A spaceship returning from the first manned space flight to Venus crashes near Sicily, releasing a fast-growing reptilian beast that rampages through Rome in one of animation master Ray Harryhausen's best fantasy films, and his own personal favourite.
The snake-tailed giant Ymir monster is also one of Harryhausen's finest creations: it has a well-defined personality and manages to evoke sympathy for its bewildered plight.
The Ymir's fight with an elephant and the Roman locations - especially the climactic Colosseum battle - add unique touches to this minor classic.
