In the mid-80's I recall watching a marathon of classical movies with Ray Harryhausen-style claymation monsters, i.e. Clash of the Titans and Jason and the Argonauts. One of these had a scene where a man is attacked by a winged monkey or gargoyle on a hill with ruins like the parthenon. It looked like the little claymation gargoyle from The Golden Voyage of Sinbad, but human-sized. I know this is a tough one.
