David Wayne plays a man seeking the Fountain of Youth . His granddaughter remarks she could never date anyone from the Twilight Zone. In "The Twilight Zone" (Season 1, episode 6), Wayne portrayed Walter Bedeker, who makes a deal to achieve immortality.
Ted McGinley and Lynda Goodfriend were cast members on "Happy Days".
The "Fountain of Youth" segment appears to have served as inspiration for the film Cocoon (1985), which was released a scant two years later.
