The 50-year-old actor, who last month revealed he is HIV positive, has reportedly been flaunting the idea of a memoir to several publishers but some have baulked at the huge sum, with one insisting that because much of his life is lived in the public eye there cannot be a lot we don't know.

A major publishing house veteran - who didn't wish to be named in case his company took on the book - told the New York Post's Page Six column: "When Charlie starred in 'Two and a Half Men', it was a funny comedy, but the idea of $10 million is even funnier.

"So much of his life has played out in public, and so much is sordid - in this case there may be too much information. What’s left to find out?"

The actor - who has previously claimed he has poetry in his "fingertips" - may not have to wait much time for a book deal though as he's reportedly been inundated with offers.

Publisher Judith Regan has expressed an interest, saying: "I would like to publish his autobiography as an epic poem."

Last week, it was reported that Charlie's manager Mark Burg has been "buried with offers" from publishers who are desperate for the 'Anger Management' star to tell his colorful life story.

The actor revealed last month he was diagnosed with HIV four years ago and now hopes going public with his diagnosis will help reduce the stigma surrounding the disease.
