Kirk Douglas at his 2nd bar mitzvah with Michael Douglas & Catherine Zeta-Jones. Los Angeles - 09/12/99

The Spartacus actor, 91, has written three autobiographical books already and has just released his fourth, entitled Let's Face It: 90 Years Of Living, Loving, And Learning.

He says, "I said to my son Michael and Catherine, 'Write your autobiography! It may or may not be published, but when you write it you think about yourself from a different perspective. And from here you get a chance to know where you came from, where you are, and where you are going.'"
