Screenwriter Aaron Sorkin and Philip Seymour Hoffman talked about drug overdoses a few years before the actor's death. The pair worked together in 2007 on the film "Charlie Wilson's War" and confided in each other about their addictions.

The New York City medical examiner's office is expected to conduct additional toxicology and tissue tests on Hoffman, 46, whose autopsy proved inconclusive. He was found dead on Sunday surrounded by a large amount of heroin in his apartment and a needle sticking out of his arm.

Sorkin told, "Phil Hoffman and I had two things in common. We were both fathers of young children, and we were both recovering drug addicts... On breaks during rehearsals, we would sometimes slip outside... and get to swapping stories. It's not unusual to have these mini-AA meetings - people like us are the only ones to whom tales of insanity don't sound insane...

"I told him I felt lucky because I'm squeamish and can't handle needles. He told me to stay squeamish. And he said this: 'If one of us dies of an overdose, probably 10 people who were about to won't.' He meant that our deaths would make news and maybe scare someone clean."
Sorkin said Hoffman left behind an acting legacy and hopes his death is seen as a warning.
He added, "(He) did not die from an overdose of heroin - he died from heroin. We should stop implying that if he'd just taken the proper amount then everything would have been fine. He didn't die because he was partying too hard or because he was depressed - he died because he was an addict on a day of the week with a y in it. He'll have his well-earned legacy... his Truman Capote and his Academy Award. Let's add to that 10 people who were about to die who won't now."

Meanwhile, Hoffman's playwright friend David Bar Katz has filed a $50 million lawsuit against National Enquirer publisher America Media, Inc., for publishing fake quotes suggesting he and Hoffman were lovers.
