Henry Fonda
DVD cover for the 1967 movie 'Yours, Mine, and Ours,' starring Henry Fonda and Lucille Ball as a widow and widower, with 18 children between them, who decide to get married. The film was a hit despite being a stretch in ages for the two principals: Ball was 56 years old, and Fonda 62, when the film was released. (And Ball's character gets pregnant in the course of the film!)
A 2005 remake of the film starred Dennis Quaid and Rene Russo in the Fonda and Ball roles.
