(19 July 1966 - 16 August 1968) (divorced)
Mia Farrow met Frank in 1964 at 20th Century Fox, when she was playing the lovelorn daughter in the TV version of the novel Peyton Place. She was no stranger to the ways of Hollywood and New York but looked the part of the innocent waif. Press speculation about the couple began less than a year into the relationship, when Frank took Mia and a group of his older friends on a yacht cruise along the eastern seaboard. She bristled when people made cracks about their age difference — Dean Martin’s was that he had a bottle of Scotch older than Mia. Later, after a brief estrangement, Frank asked her to marry him, and she accepted. He bought an $85,000 diamond engagement ring and he presented it to her — in a cake box — during a transcontinental flight.
Yet Frank doubted his decision to marry, and still saw Ava whenever they were in the same city at the same time. George Jacobs, Frank’s valet, thought Frank still hoped to win her back.
Frank referred to Mia as “my child bride” during their honeymoon, sat her on a stool and sang September Song to her in front of fellow house guests. It all felt, Mia has said, “a little bit like an adoption”. By early 1967, when they were away from each other making movies, it was evident that the marriage was in trouble. The actress Tiffany Bolling said she had a dalliance with Frank while on location with him in Florida for Tony Rome, a detective movie. He seemed to her to be sad and lonely, and he was drinking too much.
The terminal rift was over Mia’s career. She insisted in honouring her commitment to finish her work on Rosemary’s Baby, rather than join her husband to work on another movie.
One afternoon, without prior warning, Frank’s principal attorney, Mickey Rudin, showed up on the set of Rosemary’s Baby with separation documents drawn up and ready for signature. Mia signed where required and set off soon after for India, there to engage in meditation with the fashionable Maharishi Mahesh Yogi. Frank had her flown to Mexico a few months later for the divorce. They had been married just over two years.
