The actor and former California governor is writing an autobiography that will touch upon his recent breakup with Maria Shriver while also covering his childhood in Austria and his careers as a bodybuilder, action star and politician.
"This book will not be a tell-all," a source tells PEOPLE.
Schwarzenegger, 64, will work on the book, tentatively titled Total Recall: My Unbelievably True Life Story, in between shooting scenes for his next film The Expendables 2, with Sylvester Stallone.
"He has been keeping notes and working on the book for over a year," his spokesman Adam Mendelsohn tells PEOPLE. "He didn't want to write his autobiography while he was governor."
Adds Jonathan Karp of publisher Simon & Schuster: "Nobody has a life story even close to his. Truly, Arnold is one of the most fascinating figures of our time."
