The Dark Crystal is a 1982 British-American fantasy film directed by Jim Henson and Frank Oz. Although marketed as a family film, it was notably darker than previous material created by them. The animatronics used in the film were considered groundbreaking. The primary concept artist was the fantasy illustrator Brian Froud, famous for his distinctive faerie and dwarf designs. Froud also collaborated with Henson and Oz for their next project, the 1986 film Labyrinth, which was notably more light-hearted than The Dark Crystal. The film stars the voices of Stephen Garlick, Lisa Maxwell and Billie Whitelaw.
