Interesting story here. It appears that Jack Nicholson has come out and said, "I told him so." This is in reference to an apparent conversation between the original actor who played The Joker to the new Joker. He claims to have told Ledger the role was extremely demanding. This is something any movie fan understood already. Surely, Ledger knew this, but wasn't prepared for it to be this difficult. The alleged cause of his death, an overdose of sleeping pills, is undoubtedly connected to the mentally grueling role of The Joker. And I can't say that I didn't say this before. Right when I heard of the death, it was the first thing I thought. Playing The Joker isn't just another villain. You'll see it for yourself when the movie comes out.
