The first trailer for Spike TV's new documentary "I am Heath Ledger" is here, and grab a tissue because it's a heartbreaker.

Released on Tuesday — what would have been Ledger's 38th birthday — the trailer shows highlights from the documentary, which tells the life story of the "Brokeback Mountain" star, who died from an accidental drug overdose in 2008.

The feature-length documentary features never-before-seen home movie footage of the Academy Award winner, who was just 28 when he passed away.

In 2009, Ledger became the second performer in history to win a posthumous Oscar in an acting category when he won the Best Supporting Actor award for his riveting portrayal of The Joker in "The Dark Knight."

The actor's grieving family — father, Kim, mother, Sally, and sister, Kate — accepted the award on his behalf.

Ledger also left behind his own daughter, Matilda, now 11, whose mom is Ledger's ex-girlfriend and "Brokeback Mountain" co-star Michelle Williams.

"I Am Heath Ledger" makes its debut at New York's Tribeca Film Festival on April 23. It airs on Spike TV on May 17.
