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)
