The title of Michael Douglas' new memoir is One Helluva Ride, and the 82-year-old Oscar winner definitely delivers that for readers. In the late '90s, when Douglas became serious with Catherine Zeta-Jones, she warned him that she wasn't interested in dating him unless they were monogamous. I told her, Wait here, I have to make five quick calls,' he writes, shocking the Chicago star, 57, who exclaimed, Five? You have to make five calls?! 32 Michael Douglas met Catherine Zeta-Jones at the Deauville Film Festival in 1998. They're pictured above.

Getty Images I made sure they all lived in different cities, he writes of the various women he was involved with at the time, which felt like a respectful way to be nonmonogamous. None of them asked for a commitment or even asked what else I was up to. I am sure they were seeing other people, too. Years earlier, Douglas, then an unknown actor, had shared an Upper West Side apartment with another struggling actor named Danny DeVito. The two devised an old-fashioned warning if one or the other was entertaining anyone - a sock on the doorknob. Clearly, Douglas was busy entertaining during this time span, as there were some periods where Danny found himself living more outside the apartment than in. 32 Douglas writes in his just-released memoir that he excused himself to call five women after she laid down that boundary.

Getty Images He also had an affair when he was about 18 with a friend of his mother's. She was my Mrs. Robinson - she taught me a lot about women and what women liked, and it was very helpful information for a young man, he writes. Honestly, The Graduate' felt like a documentary when I watched it. Douglas also writes poignantly about his childhood and his father, the late movie star Kirk Douglas, his volcanic temper and his unhappy marriage to Michael's mother, Diana Dill.
