Krull

The imminent wedding of Prince Colwyn (Kenneth Marshall) and Princess Lyssa (Lysette Anthony) seems to have secured peace between their two communities - until they are attacked by the Slayers and their leader, the hideous Beast. Lyssa is kidnapped and taken to the Black Fortress, so Colwyn sets out to save her, armed with a magical key known as the Glaive. (Sony Pictures Home Entertainment)
