Jack Nicholson warned Heath Ledger not to take the sleeping pill Ambien.
The 70-year-old Oscar-winning star - who played The Joker in the original
'Batman' film, the role Ledger plays in new movie 'The Dark Knight' - warned
the 28-year-old insomniac of the dangers of the prescription drug.

Nicholson said: "Heath's death is tragic news. I warned him about Ambien. I
took it once and somebody called me in the middle of the night and I woke up
in my car 50 yards from my house. I almost drove off a cliff. I didn't know
where I was.
"Ambien can get you. Not through excessive use, it's just some people react
more strongly than others."
Ledger - who confessed to suffering from insomnia after playing The Joker -
was found dead in his New York apartment on Tuesday morning (22.01.08) with
pills scattered around his naked body.
