Backstage at the Oscars on Sunday night, where her brother was awarded a posthumous supporting actor's award, Kate Ledger told reporters that her family is very much in the loop on his final movie. “We've seen a little bit of the footage,” she said of Terry Gilliam's “The Imaginarium of Doctor Parnassus,” Heath Ledger's last film. “I think it's going to be amazing.” But the comments only highlighted a larger question: When will U.S. audiences get to see it? The head-trippy “Parnassus,” about a traveling magician who gives customers more than they bargained for, is a joint production of financial entity Grosvenor Park and sales mogul Samuel Hadida of Davis Films. Ledger died early last year, halting the film mid-production. The project's fate was thrown into question until Jude Law, Colin Farrell and Johnny Depp stepped in, with all three part of an elaborate work-around that has the actors playing different parts of Ledger's role. That saved the production. But the sales process since then has been nearly as complicated. “This movie stars Heath Ledger in his final performance -- it will get a deal and come out in the U.S.,” said one indie film veteran. “But it's no accident that it's taking this long.”
