Those wishing to see Heath Ledger's final performance should not fear. Movie bosses have vowed that his final film will not be digitally modified or altered, even though the actor never got to complete shooting before his tragic death.

Despite being midway through filming on The Imaginarium Of Doctor Parnassus when Heath’s sudden death was announced, director Terry Gilliam enlisted the help of Johnny Depp, Colin Farrell and Jude Law to complete the project in honour of the late Ledger.

A statement released by the movie's producers reads: "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.

"Each of the parts played by Johnny, Colin and Jude is representative of the many aspects of the character that Heath was playing."

Gilliam adds: "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."

Heath was found dead earlier this year having been killed by an accidental overdose of prescription medication.
