Ledger wanted to be a director

Heath Ledger's life is the subject of a new documentary which offers an intimate portrait of the young star through his own lens. Ledger died at the age of 28 due to a mixture of prescription drugs.

In the trailer for Spike TV and Network Entertainment's I Am Heath Ledger, friends and family recount Ledger's love for cameras, reported Entertainment Weekly.

"He was always a director, acting was just a way to get there," Trevor DiCarlo, a childhood friend, says in the preview.

I Am Heath Ledger will premiere at the Tribeca Film Festival on April 23 before hitting select theaters on May 3. The film explores Ledger's rise with roles in 10 Things I Hate About You, The Patriot, Brokeback Mountain, The Dark Knight and Monster's Ball.

Naomi Watts, Ben Mendelsohn, director Ang Lee, and Ledger's family and friends are some of the interviewed subjects.

"He wanted fame, and then when he got it, he didn't want it," filmmaker Matt Amato says.

Ledger's story has already been explored in the docu-series 'Too Young to Die' in which his father, Kim Ledger, revealed pages of his Joker diary.
