The Monkey's Uncle (1965)
The Monkey's Uncle is a 1965 Walt Disney production starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello as his girlfriend, Jennifer. The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" (a legal arrangement resulting from an experiment to raise Stanley as a human); Stanley otherwise has little relevance to the plot. Jones invents a man-powered airplane and a sleep-learning system. The film is a sequel to the 1964 film The Misadventures of Merlin Jones.
