When the first US rocket ship to Venus crashes in the Mediterranean on its return, it unleashes its top-secret cargo: an ever-growing, lizard-like space creature! As the world erupts into panic, the strange Venusian beast runs amok across Italy, hurtling towards a pyrotechnic climax at the Roman Colosseum. Special effects wizard Ray Harryhausen’s concentrated artistry succeeds in investing his Ymir creation with personality and soul, making 20 Million Miles To Earth one of the supreme showcases of his talent.
