Structure at a glance
- Inciting incident
- Page 32, 20% of the script: Romilly explains that gravitational anomalies led to the discovery of a wormhole near Saturn that appeared forty-eight years ago and leads to another galaxy, placed there by unknown beings they call 'They.'
- Act 1 break
- Page 43, 27% of the script: Cooper launches into space, leaving Earth and his family behind to begin the interstellar mission.
- Midpoint
- Page 84, 54% of the script: Cooper tells the crew they must choose between Dr. Mann's ice world and Edmunds' desert planet because they lack fuel to visit both; Brand argues for Edmunds' planet based on her field expertise and Gargantua's sterilizing radiation, but Cooper decides they will go to Dr. Mann's planet because he is still transmitting.
- Act 2 break
- Page 127, 81% of the script: Cooper and Brand successfully dock with the damaged Endurance after Dr. Mann's betrayal, preparing for the final sacrifice at Gargantua.
- Climax
- Page 146, 93% of the script: Cooper races faster down the world lines, explaining to Tars that the beings have infinite time and space but no way to find what they need, but he can find Murph through love and tell her how to find the moment, then looks at the watch on the shelf and realizes he can tell her how to save the world.
- Peak tension
- 8.4 out of 10, reached about 74% of the way through; the script averages 6.7.
- Average scene length
- 1.1 pages
Structural personality
This is a three-act epic that uses relativity and time dilation as both scientific concept and emotional engine. Act One (scenes 1-55) establishes Earth's dying state and Cooper's recruitment, ending with his devastating departure. Act Two (scenes 56-272) is the longest section—the deep space mission itself—where the crew visits Miller's planet (losing years to time dilation), then Dr. Mann's planet (where betrayal nearly destroys them). The act break at scene 272 marks their survival of Mann's sabotage and the decision to use Gargantua's gravity. Act Three (scenes 273-367) accelerates into the tesseract sequence, Cooper's communication across time to Murph, and the resolution where he's reunited with his aged daughter before departing to find Brand. The structure is deceptively straightforward but emotionally complex: it's a linear journey outward that becomes a circular journey inward (through the tesseract back to Murph's bedroom). The script uses extreme time dilation to create parallel timelines—Cooper ages slowly while Murph ages rapidly—turning what could be a standard space adventure into a meditation on parental love across impossible distances.
Pacing
The pacing is deliberately uneven, mirroring the time dilation concept. Act One moves quickly through 55 scenes establishing the mission. Act Two expands massively (scenes 56-272, over 200 scenes) to contain the bulk of space exploration, with the Miller's planet sequence (scenes 108-153) creating the first major time jump where they lose 23 years in what feels like hours. The Dr. Mann betrayal sequence (scenes 163-272) accelerates into intense action. Act Three compresses again, with the tesseract sequence (scenes 320-348) using rapid cross-cutting between different time periods in Murph's bedroom to create urgency and emotional catharsis. The final scenes (349-367) provide denouement across two locations: Cooper Station and Edmunds' planet.
