Soon after Heath Ledger’s untimely death (ultimately ruled an accident) a few weeks ago, there was a rumor floating around that Johnny Depp would step in to save Terry Gilliam’s Imaginarium of Dr. Parnassus by playing the “mirror-world” Heath. (“There is a point in the film when Heath falls through a magic mirror. He could change into another character after that and that is where Johnny would come in.“) As it turns out, the truth is even more interesting. According to AICN, Johnny Depp, Jude Law and Colin Farrell have all signed on for Imaginarium to pay tribute to Ledger and to help salvage his final performance. All class acts…here’s hoping Gilliam can make something special out of Ledger’s final bow.
