Heath Ledger's last film, Terry Gilliam's fantastical The Imaginarium of Doctor Parnassus, will in all likelihood debut at the Cannes Film Festival in mid-May, The Hollywood Reporter's Risky Biz blog reported.

The film will be released around autumn, though there's still no U.S. distributor; a Cannes screening will give media and fans a first look at the movie, which was midway through production when Ledger died unexpectedly in January 2008. Johnny Depp, Colin Farrell and Jude Law all stepped in to play different parts of Ledger's role after the actor died.

The film centers on a traveling carnival that gives patrons more than they bargain for. It's been a lengthy post-production process, with Gilliam (Time Bandits) tweaking it for months.
