Terry Gilliam's The Imaginarium of Doctor Parnassus is back to filming this week in Vancouver, Canada, Gilliam and the U.K.-Canadian co-production's producers said Monday.

According to The Hollywood Reporter, the filmmakers also confirmed widespread rumors that Johnny Depp, Colin Farrell and Jude Law will participate in the completion of the film, which shut down after the sudden death of actor Heath Ledger on Jan. 22.

"Since the format of the story allows for the preservation of his entire performance, at no point will Heath's work be modified or altered through the use of digital technology," the producers said in a statement. "Each of the parts played by Johnny, Colin and Jude is representative of the many aspects of the character that Heath was playing."

"I am grateful to Johnny, Colin and Jude for coming on board and to everyone else who has made it possible for us to finish the film," Gilliam said. "I am delighted that Heath's brilliant performance can be shared with the world. We are looking forward to finishing the movie and, through the film, with a modicum of humility, being able to touch people's hearts and souls as Heath was able to do."

The cast also includes Christopher Plummer, Verne Troyer, Andrew Garfield, Lily Cole and Tom Waits. The modern-day fantasy adventure film was written by Gilliam and Charles McKeown and produced by William Vince, Amy Gilliam and Samuel Hadida.

The Imaginarium of Doctor Parnassus was released December 25th, 2009 and stars Johnny Depp, Colin Farrell, Heath Ledger, Christopher Plummer, Jude Law, Lily Cole, Peter Stormare, Tom Waits. The film is directed by Terry Gilliam.
