Passage: Another common use of the theme is as a prison for villains or demons. The idea is used in the first two Superman movies starring Christopher Reeve where Kryptonian villains were sentenced to the Phantom Zone from where they eventually escaped. An almost exactly parallel use of the idea is presented in the campy cult film The Adventures of Buckaroo Banzai Across the 8th Dimension, where the "8th dimension" is essentially a "phantom zone" used to imprison the villainous Red Lectroids. Uses in horror films include the 1986 film From Beyond (based on the H. P. Lovecraft story of the same name) where a scientific experiment induces the experimenters to perceive aliens from a parallel universe, with bad results. The 1987 John Carpenter film Prince of Darkness is based on the premise that the essence of a being described as Satan, trapped in a glass canister and found in an abandoned church in Los Angeles, is actually an alien being that is the 'son' of something even more evil and powerful, trapped in another universe. The protagonists accidentally free the creature, who then attempts to release his "father" by reaching in through a mirror.

Passage: The next film directed by Lean was The Passionate Friends (1949), an atypical Lean film, but one which marked his first occasion to work with Claude Rains, who played the husband of a woman (Todd) torn between him and an old flame (Howard). The Passionate Friends was the first of three films to feature the actress Ann Todd, who became his third wife. Madeleine (1950), set in Victorian-era Glasgow is about an 1857 cause celebre with Todd's lead character accused of murdering a former lover. "Once more", writes film critic David Thomson "Lean settles on the pressing need for propriety, but not before the film has put its characters and the audience through a wringer of contradictory feelings." The last of the films with Todd, The Sound Barrier (1952), has a screenplay by the playwright Terence Rattigan and was the first of his three films for Sir Alexander Korda's London Films. Hobson's Choice (1954), with Charles Laughton in the lead, was based on the play by Harold Brighouse.
