This $10 million production is taken from the only children's novel done by master spy author Ian Fleming. Caractacus Potts (Dick Van Dyke) is an eccentric inventor, widower and family man who invents a magical car that can float and fly in addition to the usual road travel. The evil Baron Bombast (Gert Frobe) tries to steal the car and the inventor, but he grabs Potts' eccentric father (Lionel Jeffries) by mistake. Soon the family and candy heir Totally Scrumptious (Sally Ann Howes) are off to rescue grandpa, who still believes he is in the British Army fighting in India. They fly to a fantasy land where all children are jailed, and the adults must rescue the children to insure a safe family reunion. British comedy legend Benny Hill plays the role of the Toymaker. Eleven songs are presented by Robert and Richard Sherman, who provided the memorable music for another Van Dyke film, Mary Poppins.
