Released on what would have been the actor's 38th birthday, the trailer for 'I Am Heath Ledger' promises to bring a whole lot of emotions to the table once it's released.

Billed as "an intimate look at Heath through the lens of his own camera" 'I Am Heath Ledger' promises to showcase a treasure trove of never-before-seen footage, and features interviews from those who knew Heath best including close friends, family members, and industry peers, such as actors Naomi Watts, Ben Mendelsohn, Djimon Hounsou, and Emile Hirsch, directors Ang Lee and Catherine Hardwicke, musicians Ben Harper, Justin Vernon, N'fa, and Grace Woodroofe, and the Ledger family.

The 90 minute doc will premiere at Tribeca Film Festival on April 23rd before debuting on Spike TV in May.
