"Labyrinth" opened in American theaters on June 27, 1986. The film received a Royal Charity premiere at the London Film Festival on December 1, 1986, with Charles, Prince of Wales and Diana, Princess of Wales in attendance. Jim Henson, Brian Henson, Brian Froud, Jennifer Connelly, and the animatronic creature Ludo were all present to support the film. The royal premiere brought the film a significant level of media coverage in the United Kingdom and an article that appeared in "The Sun" quoted the Princess of Wales as remarking, "Isn't he wonderful!" upon being introduced to Ludo.
