The Happiest Millionaire (1967)

A happy and unbelievably lucky young Irish immigrant, John Lawless, lands a job as the butler of an unconventional millionaire, Biddle. His daughter, Cordelia Drexel Biddle, tires of the unusual antics of her father–especially since the nice young men around town all fear him. Wouldn’t you fear a father-in-law that keeps alligators for pets and teaches boxing at his daily Bible classes?
