Krull is a 1983 British-American heroic fantasy-science fiction film directed by Peter Yates and starring Ken Marshall and Lysette Anthony. The film includes early screen roles for actors Liam Neeson and Robbie Coltrane. A narrator describes a prophecy regarding "a girl of ancient name that shall become queen, that she shall choose a king, and that together they shall rule their world, and that their son shall rule the galaxy". The planet Krull is invaded by an entity known as "The Beast" and his army of "Slayers", who travel the galaxy in a mountain-like spaceship called the Black Fortress. In a ceremony involving exchanging a handful of flame between the newlyweds, Prince Colwyn and Princess Lyssa attempt to marry and form an alliance between their rival kingdoms in the hope that their combined forces can defeat the Beast's army. A prophecy foretells that Lyssa will bear a child destined to rule the galaxy. The Beast has his Slayers attack the wedding before it is concluded.
