According to an extensive New York profile out today, Heath Ledger spent his final days deeply engrossed in researching and writing a script based on the life and death of Nick Drake. In case you missed the whole Drake resurgence of the late `90s (spurred by Volkswagen's usage of his song "Pink Moon" in a now-classic advert), he was an English singer-songwriter who battled insomnia and depression before overdosing in his bed at age 26. Sounds sickeningly familiar, right? According to the piece, Heath's last weeks involved saying goodbye to the Nice Guy character he'd played publicly since the birth of his daughter Matilda and falling into another role altogether: a depressed, masked public figure who, consumed with writing the Drake screenplay, just might have got too close to his subject.
