The idea of Johnny Depp, Colin Farrell and Jude Law co-performing or additionally playing Heath Ledger‘s character in Terry Gilliam‘s The Imaginarium of Doctor Parnassus is a noble gesture on the part of the actors. Admirable, compassionate. It’s going to result in a slightly confusing narrative, but Gilliam’s films unfold that way regardless so no harm done.
Ledger’s footage was shot in London (i.e., mainly exteriors) — the other three will perform green-screen scenes. The common character, “Tony,” is “transported into three separate dimensions [that] Ledger accesses via a paranormal mirror, and which will “now be inhabitated by Depp, Law, and Farrell,” an Variety/AICN story informed.
