Arnold Schwarzenegger to tell all about his 'unbelievably true life story' In crisis communications terms this is what is called a "pivot" moment for Mr Schwarzenegger. Having suffered disgrace, apologised, and spent an acceptable period in the celebrity wilderness, it is time for the fightback, and he is coming back with all guns blazing. At the forefront of his PR blitz will be a new autobiography, which he intends to be a kind of literary Uzi 9mm. Much hyped, and much anticipated, the October 1 launch of Total Recall: My Unbelievably True Life Story will be accompanied by a high profile television interview. The word in publishing circles is Mr Schwarzenegger will pull no punches. For the first time he will offer his side of the story over how he fathered an illegitimate son with his Guatemalan-born housekeeper Mildred Baena. Even by the standards of American politicians the scandal was explosive. Whispers had circulated for years that the boy, Joseph, was Mr Schwarzenegger's son, but the truth only became apparent to Miss Shriver as he grew up to look like his father. Miss Shriver had also been pregnant with the couple's fourth child, Christopher, at the same time Miss Baena was pregnant. Mr Schwarzenegger's publishers, Simon & Schuster, have said the book will be "candid" and that he "spares nothing in sharing his amazing story." In a slick, Hollywood-style trailer, he declares: "If my life was a movie no-one would believe it, the directions I've chosen, the careers I have conquered. This story you know. So are you ready for the story you don't? The question now for Mr Schwarzenegger is whether there will be a personal cost as he tells all and tries to regain public sympathy. Among those not sure they're ready may be Maria Shriver herself. According to Laurence Leamer, who wrote the 2005 Schwarzenegger biography Fantastic, Miss Shriver had, even a few weeks ago, no idea about the contents of the book. In an article for Newsweek, Mr Leamer also revealed that Miss Shriver had asked her cheating husband to go to therapy with her to save the marriage, but that he only went once. The relationships in the Schwarzenegger clan appear complicated. He and Miss Shriver still attend the same church in Santa Monica on Sundays. And earlier this year they were seen shopping together for furniture as she prepared to move into a new $12 million home. The divorce has yet to be finalised but both parties have successfully, and unusually in Hollywood, avoided leaks and public mud slinging. But soon after their separation the couple's eldest son Patrick, 19, who is forging his own career as a clothing company owner, model and actor, changed his name to Shriver on his Twitter account. The couple's eldest daughter Katherine, 22, already the author of a self-help book, recently graduated from the University of California with a communications degree and is following in the footsteps of her journalist mother. Mr Schwarzenegger's overriding concern throughout the family crisis is said to have been his children, who are the "light and centre" of his life. But he appears to have accepted there will be no reconciliation with his wife of 25 years. According to Newsweek, at one point he told a friend: "I think things will work out OK with Maria, but if they don't, I'm getting me a 20-year-old honey." In July, gossip websites reported that he had been seen with a "25-ish-year-old brunette" at a West Hollywood restaurant. The swagger of one of the world's richest movie stars would appear to be back. A few weeks ago Mr Schwarzenegger was seen driving around Santa Monica in a monster truck, a $250,000 Mercedes-Benz UNIMOG, often used by the military. He still has his office not far from Muscle Beach where his would-be body-building successors strut and preen. Close by is a tobacco shop where he still buys the cigars he smoked when he was the "Governator." From here he is co-ordinating the operation to save his long term reputation. His book has been co-written with Peter Petre, a former executive editor of Fortune magazine who also co-wrote autobiographies of former Federal Reserve chairman Alan Greenspan and General Norman Schwarzkopf, who commanded coalition forces in the Gulf War. Undoubtedly, Mr Schwarzenegger hopes Petre's pedigree will help the book to be considered a serious historical tome. On Monday, he will launch another prong of his comeback with the opening of the Schwarzenegger Institute for State and Global Policy, a think tank at the University of Southern California. Its $20 million funding will come partly from money Mr Schwarzenegger raised, and partly from his own pocket. He will have the academic title of Downey Professor of State and Global Policy. The opening will be attended by heavyweight politicians including former Republican presidential candidate John McCain and former Democratic Senate Majority Leader Tom Daschle, along with Hollywood power players James Cameron and Ron Meyer, the president of Universal Studios. The third prong sees Mr Schwarzenegger return to the silver screen, and in this he has been helped by his friend Sylvester Stallone. The pair appeared together in action blockbuster The Expendables 2 last month, and next year they will play prison cellmates in The Tomb. In 2013 Mr Schwarzengger will also be seen in his first leading role for a decade, playing a sheriff in The Last Stand. Chris Lehane, a crisis communications expert and former White House adviser to President Bill Clinton, said Mr Schwarzenegger's comeback strategy could work. "He handled it the right way from the start," Mr Lehane told The Sunday Telegraph: "He took full responsibility and apologised, and avoided digging a deeper hole in what was already a very deep hole. That's given him the option to orchestrate a long term comeback. Part of that comeback is having some time between events. You can't just apologise and turn the page the next day. Now he can do a movie, he was a leader on public policy issues such as climate change, and he has a book. All of these are part of a three point pivot that allows him to focus on the future and rebuild his image. It's a marathon not a sprint. What happened is always going to be part of his story line. But there is a reason people paid money to see him on screen, because he's very likeable. His comeback is part of the story line.
