The Imaginarium of Doctor Parnassus is an upcoming fantasy film directed by Terry Gilliam and written by Gilliam and Charles McKeown. The film follows the leader of a travelling theatre troupe who, having made a deal with the Devil, takes audience members through a magical mirror to explore their imaginations.

Christopher Plummer, Tom Waits, and Heath Ledger star in the film, though Ledger's death one-third of the way through filming caused production to be temporarily suspended.
