Heath Ledger's final role will be left intact. The scenes he has already filmed will be left in the movie, and 3 other actors will play the character during the course of the movie. I'm not sure exactly how this will work out but it sounds interesting. Jude, Johnny & Colin to Assume Heath's Last Role - Movie News, Colin Farrell, Heath Ledger, Johnny Depp, Jude Law : People.com Johnny Depp, Jude Law, and Colin Farrell are the three actors chosen to step into the various "versions" of Tony in "The Imaginarium of Doctor Parnassus". The film deals with magic and will be rewritten a bit to allow for Ledger's scenes to still be used. This will be interesting for sure.
