I was going to write a post entitled 10 Things to Remember about Heath Ledger before I realized I didn't know 10 things about Heath Ledger to begin with. And that realization partly explains why his death is so tragic; Heath was one of the guys you didn't see in the tabloids or hear about in nasty rumors. He had a private life that seemed devoid of the indulgences and scandals so common with other young stars and starlets. Heath seemed like one of the "good guys."
I haven't seen Brokeback Mountain (though I plan to) but I know Mr. Ledger took his job seriously. I know he took roles like Casanova to keep his fans happy while he yearned to explore more complex characters. In the New York Times article describing his death, one of his quotes summed up his acting ambitions: there are many stories inside of me and a lot I want to achieve outside of one flat note.
The Dark Knight is due out this summer and by that time more information about the conditions surrounding Heath Ledger's death will be available. No matter what details may arise, nothing will prevent this from being a sad and tragic event.
