Role: Ullman

Synopsis: A human-male named Farrow finds a crashed spaceship, goes inside, and discovers three astronauts - one dead, two unconscious. He carries the two unconscious ones to his cave and, after they revive, shows them an old book with a photo of New York City in the year 2503. Shocked, the astronauts figure that while they left Earth in the year 1980, they've somehow come back to Earth more than a thousand years later, and that apes now rule the planet! Farrow is killed defending the astronauts who are captured by apes, tried, and thrown into a cell. They escape in company with a sympathetic chimp named Galen and begin a series of adventures.
