Given the fact that Heath Ledger protested against the war in Iraq and the greed of the oil companies, the only possible conclusion that I can come to is that the CIA murdered him. His "suspicious" death is very similar to that of Marilyn Monroe and as you'll recall she........Hang on the medication trolley has arrived. I'll finish this later.

But yeah. It is very sad. He was just getting noticed a lot more and yeah, the death of Heath will be forever remembered in my mind as one of the greatest young actors.

Maybe my question should be wansered by Cesar Romero and Jack Nicholson, that played the Joker. Unfortunatly, Mr. Romero dies in 1994 and I never heard him talking about this character.

In my poor opinion I think he gets involved to much with the role. Maybe he wanted take a lot of this psychopath character. I have my doubts about and I don’t believe in CIA conspiracy.

Heath Ledger thought landing the demanding role of the Joker was a dream come true - but now some think it was a nightmare that led to his tragic death.

Jack Nicholson, who played the Joker in 1989 - and who was furious he wasn't consulted about the creepy role - offered a cryptic comment when told Ledger was dead.

"Well," Nicholson told reporters in London early Wednesday, "I warned him."

Though the remark was ambiguous, there's no question the role in the movie earmarked as this summer's blockbuster took a frightening toll.

Ledger recently told reporters he "slept an average of two hours a night" while playing "a psychopathic, mass-murdering, schizophrenic clown with zero empathy ...

"I couldn't stop thinking. My body was exhausted, and my mind was still going."

Prescription drugs didn't help, he said.

Ledger's ghastly image as the Clown Prince of Crime in "Dark Knight" has been an Internet sensation since trailers were released in December, featuring Ledger in full death's-head mode.

His face chalk-white, his hair green and his mouth a sliced red grimace, the handsome 28-year-old Australian actor looked frighteningly true to the character in the Alan Moore graphic novel, "Batman: The Killing Joke."

The movie wrapped filming in the fall - right after Ledger's breakup with actress Michelle Williams - and post-production work finished not long after.

While "Dark Knight" is the film that will stand as Ledger's cinematic gravestone, insiders say the flick, set for a July 18 release with Christian Bale as Batman, won't suffer from his death.

"Ledger's portrayal of the Joker is already one of the most anticipated screen characters of the whole year," says Gitesh Pandya, editor of the movie tracking site boxofficeguru.com

"I think most of the audience will still be there. If anything, I would think the marketing of his character might be scaled down a bit.

"The Joker is a character where you could go over-the-top with marketing. The studio might scale that back a bit in the next few months, just to be respectful."

Tony Timpone, editor of the fantasy magazine Fangoria, said the movie should do well, despite the "cloud over it" from Ledger's death.

"It's going to be tough, because the Joker is such an indelible character, and Heath was such an indelible actor. It could be tough to disassociate ourselves from reality. Because the movie looks like it's going to be so dark, and his life had such a dark end."

Critic and film historian Leonard Maltin said Ledger's death will heighten curiosity about the movie - and certainly won't hurt the box office.

"This is sad and so different from any previous examples, because the film has such an enormous built-in audience; people will go anyway, but there's no question it could cast something of a pall over the film," Maltin said.

"It says something about the curious nature of film, that someone can be so alive onscreen when we're all too aware that they've passed. It underscores how we're mortal, and films are immortal."
