Hollywood veteran Jack Nicholson insists stories claiming he warned Heath Ledger about the dangers of sleeping pills are not true - stating he never even met the tragic star. The As Good As It Gets legend was asked how he felt about the Brokeback Mountain actor's death last month (Jan08) by photographers in London and he was quoted as saying, "I told him so." However, the 70-year-old star, whose role as the Joker in Batman was reprised by Ledger just before his death, states he was misquoted and was simply warning everyone against using that brand of pills. He says, "What I actually said was, 'I warned them.' I had a bad experience with those sleeping pills (that Ledger apparently took). "I took one of these pills and had just gone to sleep when I had a phone call to go to an emergency at a friend's house. I jumped up, went outside and some time later woke up on the driveway. "It sounds amusing but I live in the mountains and it could of been worse. I didn't know Heath Ledger, but I know those pills." Ledger was found dead in his New York apartment last month (22Jan08) at the age of 28. An autopsy failed to reveal the cause of death, and police are still awaiting the results of a toxicology test to asses if sleeping pills found in his apartment played a part in his death.
