A trailer was released recently for Heath Ledger's last film, 'The Imaginarium of Doctor Parnassus,' which is about a 1,000 year old doctor who leads a traveling theater troupe and then makes a deal with the devil.

Ledger, who passed away in January of this year before the film was finished, played a mysterious man named Tony who joined the troupe. After Ledger's untimely death, actors Colin Farrell, Jude Law and Johnny Depp stepped into the role of Tony.

The film is scheduled for release in 2009.
