One of Ray Harryhausen's earlier films, this is among the best monster-on-the-rampage movies from the fifties and sixties. An expedition to Venus returns to Earth, bringing with them a strange alien creature which soon begins to grow to giant proportions. What makes this film is Harryhausen's superb animation. The alien 'Ymir' is imaginatively-designed and is an interesting and, as with a lot of Harryhausen's monsters, you feel real sympathy for it. Look quickly for a cameo from Harryhausen as a zoo keeper
