Two top U.S. production companies are rumoured to be battling for the screen rights to the book - My Word Is My Bond - which was released in October.
The autobiography details Moore's exploits with legendary Tinseltown co-stars including Elizabeth Taylor, Lana Turner, and David Niven in the 1950s and '60s.
The thrilling tales have caught the imagination of movie bosses - with two leading Hollywood studios said to be in talks with Moore's literary agents to secure the rights to the book.
And a source close to Moore has confirmed that producers are keen to sign up an A-list star to play Moore - with Johnny Depp hotly tipped to take the role.
The source tells WENN, "The two production companies' interest in Sir Roger was heightened after they read the tales of his Hollywood exploits.
"They are keen to centre on that era ahead of his 007 days. They believe filmgoers will lap this one up and it could be a huge hit.
"The whole project is shrouded in secrecy but Sir Roger has been telling friends, with a knowingly raised eyebrow, that he's a great admirer of Johnny Depp."
