Which 1969 science fiction film ends with a twenty-minute sequence showing an astronaut aging and then turning into a child orbiting Earth?

• A. Planet of the Apes
• B. Solaris
• C. Thunderball
• D. 2001: A Space Odyssey

Answer: (D)

The main idea being tested is recognizing a film by its iconic ending, where the story’s big moment hinges on a dramatic, surreal transformation. In this movie, the final sequence shows an astronaut aging in a kaleidoscopic, otherworldly environment and then turning into a child-like being who orbits Earth. That long, meditative finale is a defining moment of the film, and it’s widely associated with the director’s vision of evolution, humanity, and the cosmos. The film’s reputation rests on its pioneering visuals, minimal dialogue, and this unforgettable ending, which stands in stark contrast to typical action-packed conclusions.

As for the other options, one ends with a twist about Earth’s future rather than a cosmic transformation, another is more about psychological drama than a transformative voyage, and the last is a different genre altogether. The film with the aging-to-child sequence is the one that delivers that singular, symbolic finale.
