In this fantastical musical adventure story, adapted from the book by James Bond author Ian Fleming, widowed father and eccentric inventor Caracatus Potts (Dick Van Dyke) transforms a broken-down old car into a flying machine -- to the delight of his children (Heather Ripley & Adrian Hall), and the envy of the tantrum-prone Vulgarian king, who has outlawed children in his kingdom. The Potts family, with candy factory heiress Truly Scrumptious (Sally Ann Howes), head to the kingdom to save the day.
