Normally I wouldn't post celebrity deaths,births,etc, but since I am really looking forward to the new Batman movie, The Dark Knight, I thought it'd be pertinent.  Heath plays The Joker, and a rather disturbing character at that.  His inspiration was some of the darker graphic novels, and The Clockwork Orange.  Studying this character bothered him enough that he couldn't sleep, and during interviews was reportedly disorientated.
It's alleged that he died of a drug overdose, and people are wondering if it's in any way connected to his latest role.  It certainly adds creep-factor to watching The Joker now.
