Starcrash anyone? Christopher Plummer as the Emperor of the First Circle of the Universe. David Hasselhoff as his son, the prince with the key to stopping the evil plot of Count Zartha-aan and the League of Evil Planets. A texan police-robot and a scantily-clad space-age mercenary-lady as the hero?
No-one does Star Wars knock-offs better than Italians, evidently.
