Watch: First look at the new film about Heath Ledger's life

Almost 10 years after his death, a new documentary takes a look at the life of Heath Ledger.

The first trailer for I Am Heath Ledger - which will premiere on April 23 at the Tribeca Film Festival - was released today and shows never-before-seen home videos of the actor. The film will also feature interviews with his friends and family as well as some of the stars and movie directors he worked with.

The Australian heartthrob starred in several films including, 10 Things I Hate About You, BrokeBack Mountain and The Dark Knight before his death in January 2008. Heath was just 28 when he died.
