London, July 11 : Sir Michael Caine has revealed that his autobiography has no shocking revelations, as he has never done anything.

The 77-year-old acting legend has promised that his autobiography is full of humour, and has no hidden secrets.

"Oh no it''''s funny, it''''s more like David Niven, It''''s funny. I haven''''t got any revelations I''''ve never done anything. I''''ve been happily married for 40 years, what am I going to reveal?" the Mirror quoted him as saying.

Asked what he plans to do next, Michael said, "I just finished the second part of my autobiography and I really haven''''t the foggiest idea [what I''''ll do next] because I don''''t work very much anymore."

But he did confirm that, "I have a contract for Batman 3 but I don''''t know when it''''s going to be made. I read in the paper next April. I don''''t know."(ANI)
