I was hearing that a close friend of his was saying that he was taking sleeping pills because his role as the Joker was so dark and twisted that it wasn't allowing him to sleep at night.

With the amount of paparazzi that follow celebrities around... I think we would have known if he was a drug user. I mean, we know every time Lindsay Lohan or Amy Winehouse does a line of coke.

Who knows, like Drakiis said, the autopsy hasn't been done yet. We'll know what happened soon enough, although apparently the way he was found in his apartment did seem ridiculously suspicious.

It's a shame though. He's one of the few teen heartthrobs that actually started caring about their craft and careers, and began taking serious roles. He was fun to watch in films like The Patriot, or A Knight's Tale, but yeah, his performances in movies like Four Feathers or Broke Back were pretty powerful.

Apparently he did an incredible job as the Joker.

he was actually a drug user but his reps said that he had been clean for a year. Aparently there was something like 6 different prescription drugs found around him in their bottles. I feel really bad for his daughter she's just two years old
