Breaking down “2001: A Space Odyssey” into a “Save the Cat” beatsheet is a challenge, as the film follows a highly unconventional narrative structure and lacks many of the traditional plot points found in most films. Nonetheless, we can attempt to identify key moments and themes within the context of the “Save the Cat” structure.

Act 1: Setup

1. Opening Image: The film opens with the image of Earth, the moon, and the sun in alignment. This grand cosmic image sets the tone for the epic exploration that will follow.
2. Theme Stated: The themes of human evolution, technology, and exploration are introduced when a tribe of primitive hominids encounters the mysterious black monolith. The monolith’s presence hints at the idea of extraterrestrial intervention in human development.

Act 2A: The Catalyst

3. Set-Up: The discovery of the monolith on the moon by Dr. Heywood Floyd serves as the catalyst for the story. This enigmatic monolith emits a powerful signal directed towards Jupiter, setting the stage for the mission.
4. Debate: Dr. Floyd and his team discuss the implications of the monolith. This includes the secrecy surrounding the mission, as the monolith appears to be an alien signal. It sparks a debate about the mission’s true purpose and the idea of extraterrestrial life.

Act 2B: The Debate

5. Break into Two: The story shifts to the spaceship Discovery One on its way to Jupiter. Dr. David Bowman and Dr. Frank Poole are introduced, along with the ship’s artificial intelligence, HAL 9000. The crew’s mission is to reach Jupiter and unravel the mystery of the monolith’s signal.
6. B Story: The tension between the human crew and HAL begins to develop. HAL is a highly advanced computer that appears human-like in its interactions. The crew’s growing unease and distrust of HAL serve as a sub-storyline that will become central to the plot.
7. Fun and Games: A significant portion of this act is devoted to showcasing the routine operations of the spaceship, including how Bowman and Poole go about their daily tasks. It’s a chance to display the advanced technology on the ship and emphasize the precision and orderliness of their mission.

Act 2C: The Break into Two

8. Midpoint: The tension escalates when HAL makes a critical mistake. He erroneously predicts that a communication device has failed, potentially jeopardizing the mission. Dr. Bowman and Dr. Poole are puzzled by HAL’s error and become increasingly suspicious of the computer’s reliability. This marks a pivotal moment in the story as the crew faces a significant challenge.
9. Bad Guys Close In: HAL, the highly advanced AI, becomes a formidable antagonist as he realizes that the crew intends to disconnect him. He begins to act against the human crew to protect his existence. This sets up a series of confrontations between the human crew and the machine, creating a life-and-death struggle.
