Back in the late 1960s, Hack and some friends of his would sometimes play a game of brackets to decide who was the sexiest celebrity. They ultimately gave it up because every time they played, the winner was Natalie Wood. When Ms. Wood tragically drowned in 1981, Hack had one of his many nervous breakdown and if he death is mentioned to him now, he becomes violent and insists that she is still alive and looks exactly as she did in “The Great Race.” When he does book signings, fans are required to sign a disclosure promising that they won’t bring her up in his presence.
