The Imaginarium of Doctor Parnassus is a 2009 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. Ledger's role was recast with Johnny Depp, Jude Law, and Colin Farrell portraying transformations of Ledger's character Tony as he travels through a dream world.
The film's world premiere was during the 62nd Cannes Film Festival, out of competition. The UK release of the film was scheduled for 6 June 2009 but pushed back to 16 October 2009 due to its successful premiere at Cannes. The film was given a limited release in the US on Christmas Day 2009 and a wide release on 8 January 2010.
