I was shocked by the news today of Heath Ledger's passing. He was a great actor (and father) who I could envision working in the industry for his lifetime. Sadly, his life was cut short at the age of 28, leaving behind a two-year old daughter (Matilda Rose Ledger).
Heath has a long-list of film credits to his name. My personal favorites:
10 Things I Hate About You
A Knight's Tale
Lords of Dogtown
His forthcoming picture, The Dark Knight , in which he plays the Joker, will be released later this year.
