Terry Gilliam’s fantasy film features the last onscreen performance of the late Heath Ledger. Johnny Depp, Jude Law, and Colin Farrell signed on to play incarnations of Ledger’s character after the Oscar-winner’s death in January 2008. The actors even donated their salaries to Ledger’s young daughter, Matilda.

The Imaginarium of Doctor Parnassus hits theaters Oct. 16.

Heath Ledger’s final film was presented at the Cannes Film Festival on Friday, The Associated Press reports.

In his final performance on the silver screen, Heath — who won a posthumous Oscar for his role as The Joker in 2008’s The Dark Knight — plays Tony, a man who discovers a supernatural theater group that has the ability to travel to fantasy worlds, in The Imaginarium of Doctor Parnassus.

Directed Terry Gilliam completed the film with some pro bono help from Jude Law, Johnny Depp, and Colin Farrell, who took over Heath’s role as the character travels to make-believe realities.

The movie ends with a special dedication: “A film from Heath Ledger and friends.”

The late Heath Ledger won a posthumous Oscar for Best Supporting Actor for his performace as The Joker in The Dark Knight.

The deceased star’s family gave an emotional acceptance speech on his behalf.

“I have to say this is ever so humbling,” Heath’s father Kim Ledger said. He thanked Batman director Christopher Nolan for “allowing Heath the creative license to develop and explore this crazy Joker character.”

“Heath was such a compassionate and generous soul,” his mother Sally Bell said. “We have been truly overwhelmed by the honor and respect bestowed upon him with this award.”

Heath Ledger died of an accidental overdose in January 2008.

Heath Ledger has received a posthumous Oscar nomination on the first anniversary of his death.

The late star will battle Josh Brolin (Milk), Robert Downey Jr. (Tropic Thunder); Phillip Seymour Hoffman (Doubt) and Michael Shannon (Revolutionary Road) for the Best Supporting Actor trophy for his role as “The Joker” in 2008’s Summer blockbuster The Dark Knight. He won a Golden Globe for his performannce earlier this month.

Heath, 28, died of a prescription drug overdose at his NYC apartment on January 22, 2008.

Heath won a Best Supporting Actor prize for his role as “The Joker” in the 2008 Summer blockbuster The Dark Knight.

“I should imagine that eventually it will be going to Matilda,” Heath’s mom Sally Bell told PEOPLE Magazine in an interview from her home in Perth, Australia on Monday.

“At this stage she is only so young, but down the track she will have all these things. It will belong to her because she is part of him.”

“It is such a fantastic and wonderful legacy for his daughter,” Ms. Bell added.

“Matilda will have so many people who will be able to speak to her about her father’s abilities and [the] respect he had in the industry. That is such a wonderful legacy to leave.”

Heath Ledger was found dead in his New York City apartment last January of an accidental overdose of prescription drugs.

Heath Ledger was posthumously honored for his portrayal of the demented Joker in the Summer 2008 blockbuster The Dark Knight at the 2009 Golden Globe Awards.

The actor, who died of an overdose in January 2008, won the trophy for Best Supporting Actor in a Drama during Sunday night’s ceremony at the Hilton Hotel in Beverly Hills. Dark Knight director Christopher Nolan accepted the award for Heath. “On behalf of all of us who worked with Heath on Dark Knight, I accept this with mix of sadness and incredible pride,” Nolan said. “He will be eternally missed but he will never be forgotten.”

“We are overjoyed for him,” Heath’s dad, Kim Ledger, told PEOPLE on Sunday. “It’s wonderful.”

Robert Pattinson slammed a Los Angeles comic earlier this week after the stand-up star made jokes about the January 2008 death of actor Heath Ledger.

The Twilight heartthrob was in the audience at The Improv Club in Hollywood when a stand-up comedian performed an “impression” of Heath Ledger by collapsing on the floor and convulsing.

“Robert and his friend went nuts yelling at him,” a witness told Us Weekly. “[Robert screamed] f**k you! You suck!”

“The comic didn’t know who it was, but I’m sure he found out later!” the spywitness told Us.

The SoHo Manhattan apartment where Heath Ledger dead of an accidental overdose nearly one year ago remains empty, according to Page Six.

The three-bedroom, 4,400-square foot loft at 421 Broome Street has been listed since July with the Corcoran Group but renters are reportedly turned off by the residence’s Ledger connection and the $26,000 per month rent tab.

Long-running television crime drama Law & Order is planning one of it’s trademark “Ripped From The Headlines” episodes based on the fatal January 2008 drug overdose of Oscar-nominated actor Heath Ledger.

The episode features a male supermodel, played by Ryan Locke, who “has a great career and gets all the ladies,” says one Page Six spy. Perhaps the eeriest comparison is to Ledger’s actual death by overdose when the character “leaves a club with a girl. They have sex and do drugs, and the next morning, his friend finds him dead.”

After Heath’s passing, Johnny Depp, Jude Law, and Colin Farrell all stepped in to fill his role for the remainder of the film by playing different incarnations of his character.

The Imaginarium of Doctor Parnassus is now complete and set release in 2009.
