Jack Nicholson said Tuesday that he "warned" fellow Joker actor Heath Ledger.
The 70-year-old Oscar winner was dining at the Wolseley restaurant in London when a photographer told him about Ledger's death.
After saying, "That's awful," Jack added “I warned him," and refused to elaborate.
Later, at the premiere of his new film "The Bucket List," Nicholson reportedly said he "warns people about Ambien."
“I almost drove off a cliff once. I don’t take sleeping pills but somebody said ‘take this, it’s mild.'
“I got a call in the middle of the night, kind of an emergency, and I almost drove off a cliff 50 yards from my house, and I live up in the mountains in Aspen. So I warn people about it. But I also did not know Mr. Ledger.”
Nicholson played The Joker in the 1989 "Batman" movie; Ledger played The Joker in the upcoming "Dark Knight."
Ledger had acknowledged that his brooding character drained him physically and mentally and caused him to have trouble sleeping, a condition for which he said he took prescription pills.
According to an MTV November interview, Nicholson was asked: "What do you think of another actor, Heath Ledger, playing the Joker?"
"Let me be the way I'm not in interviews. I'm furious. I'm furious [he laughs]. They never asked me about a sequel with the Joker. I know how to do that nobody ever asked me."
