comicbook.com reports that Spike TVs "I Am" documentary series will have an episode focusing on Heath Ledger's career. His work included films like Brokeback Mountain, The Patriot, A Knight's Tale, 10 Things I Hate About You, and more. Ledger won the best-supporting-actor Oscar for his performance in The Dark Knight, but passed away from an overdose of prescription drugs before the film hit theatrical release.
