Revelation is a 2001 British supernatural thriller film directed by Stuart Urban and starring James D'Arcy, Natasha Wightman, Udo Kier and Terence Stamp.
The trail takes the three characters to (among others) a Cambridge library to research Isaac Newton's involvement in attempting to unlock the Loculus and to Rennes-le-Château and its Tour Magdala.
Father Connolly stays behind in London as backup while Mira and Jake go to Patmos and find the Loculus hidden in a crypt beneath a Greek Orthodox church and former temple to Mary Magdalene as Aphrodite.
Jake and Mira disrobe and make love within the symbol in an attempt to unlock it, experiencing a vision of themselves as Christ and Mary Magdalene before fleeing into the crypt when they hear a pursuer approaching.
The Guardian, for example, noted the film's "rag-bag of extraordinary cameos" but criticised the "vulgar heresies" on which it was based and likened the "significant, ritual sex with a beautiful alchemist" with the "clean-limbed young hero" to an Occult-based sketch in Not the Nine O'Clock News.
