Heath Ledger: "Brilliant," as called by the director of his final film.

Heath Ledger was highly appreciated by the director of his final film, The Imaginarium of Doctor Parnassus.

Terry Gilliam, the director of the film says, the late actor was more than just a cast member. He also mentioned that Ledger almost co-directed the movie.

Heath Ledger's last ever movie has had its first ever screening at the Cannes Film Festival.

Terry Gilliam, at the Cannes Film Festival this Friday said, "Heath was just brilliant at it, and he got everybody else going, everybody was just energized by Heath. He was extraordinary. He was almost exhausting because he had so much energy."

According to sources, Gilliam said, when Ledger died in January 2008 halfway into his performance, he had to "go out and find a way of finishing the film for Heath. The solution: casting Johnny Depp, Jude Law and Colin Farrell to play incarnations of Ledger during the fantasy movie.

Ledger was definitely not forgotten while he was replaced. At the end of the movie, there's a dedication: "A film from Heath Ledger and friends."
