 On July 19th, 1966, a 50-year-old Frank Sinatra wed a 21-year-old Mia Farrow. It was Frank's third wedding, and it would not be his last. Shortly after the nuptials, Farrow reneged on an agreement to co-star in the upcoming Sinatra flick, The Detective. She had a conflict with a little film called Rosemary's Baby. Sinatra's response? He had Farrow served with divorce papers on the set.
