Heath Ledger‘s final film, The Imaginarium of Doctor Parnassus, is set to premiere at the Cannes Film Festival in France on May 22nd. Ledger died at his home during a break from filming. The movie wasn’t yet finished, so three actors stepped in to help — Johnny Depp, Colin Farrell and Jude Law, all filling in as Tony, the same character that Ledger played. The fantasy film follows Dr. Parnassus (Christopher Plummer), the leader of a traveling theater group who long ago made a bet with the devil and won immortality. But when he makes another deal involving marrying off his first-born daughter when she turns 16, he regrets it as she approaches that age and tries to renegotiate.
