The People That Time Forgot is a 1977 Technicolor fantasy/adventure film based on the novel The People That Time Forgot (1918) and Out of Time's Abyss (1918) by Edgar Rice Burroughs. It was produced by Britain's Amicus Productions and directed by Kevin Connor. Like Connor's other two Burroughs-derived films, The Land That Time Forgot and At the Earth's Core, the film was distributed in the United States by American International Pictures. The film is a direct sequel to The Land That Time Forgot, which initiated the series in 1975. The story follows a rescue expedition, led by Patrick Wayne in search of his friend, played by Doug McClure, who had vanished many years before. The expedition lands on Caprona, the same fantastic prehistoric land where dinosaurs and barbarian tribes of men co-exist.
