Directed by Jim Henson and Frank Oz, and featuring Henson's signature use of puppetry and animatronics, The Dark Crystal tells the story of two Gelflings, a fictional race of elf-like fantasy creatures, who must embark on a quest to restore balance to their world through the mending of an all-powerful crystal, broken and corrupted by a malevolent race known as the  Skeksis. Stephen Garlick and Lisa Maxwell voice the protagonists, Jen and Kira.
