As a piece of cinema that Ray Harryhausen did, as the animator, it was a time when stop-motion animation was utterly acceptable to us as a proxy for fantasy – it wasn't like “oh it doesn't look very real” – it didn't matter that it wasn’t real, the fact was Harryhausen just masterfully animated these things, put them in, it looked like a special effect but you bought it and you loved it because of that.
