The actor has been working on the book since he stepped down from the position as California governor.
Arnold Schwarzenegger's ups and downs would be recorded in a memoir titled "Total Recall: My Unbelievably True Life Story". Despite the title, the book, which would be published by Simon and Schuster, reportedly will not be a tell-all.
The autobiography would include his childhood in Austria, his career as a bodybuilder, action star and then politician. It would also touch personal issues like his marriage to journalist Maria Shriver and their recent divorce.
Working on the book since 2010, the 64-year-old would divide the time between writing it and filming "The Expendables II". His spokesman Adam Mendelsohn told People, "He has been keeping notes and working on the book for over a year. He didn't want to write his autobiography while he was governor." Peter Petre is signed as co-writer.
"Truly, Arnold is one of the most fascinating figures of our time, and one of the greatest success stories in the world," said Jonathan Karp, the publisher of Simon & Schuster, in a statement. "Nobody has a life story even close to his." The publisher is expected to sell the book to foreign publishers at the Frankfurt Book Fair.
