“The influence of the future on the past” said Morel, almost inaudibly.
– Adolfo Bioy Casares.
In 1999 as an industrial engineering student, my thermodynamics professor handed us an unusual extra credit assignment: read The Invention of Morel, a 1940 novel by Adolfo Bioy Casares. The book connected my scientific and creative thinking in ways I didn’t fully understand then.
I never imagined that the second law, the law of entropy, could be so deeply poetic.
That the arrow of time, the irreversibility of all things, is not just physics. It’s the science of impermanence colliding with the most human desire imaginable: to make a moment last forever.
Two decades later, with tools that didn’t exist when I first read the novel, I finally made the film. One Week in Eternity is a 5-minute AI-assisted narrative adaptation of the novel, and a meditation on consciousness, permanence, and the price of immortality.
The Adaptation
Adapting a philosophical novel into five minutes was the first great challenge.
It means curating and redacting the most essential elements without losing meaning.
The film needed to move like memory. Selective, precise, irreversible.
Early character and location studies
Consistency
Maintaining a single character across 100+ shots in generative video is not a given. It requires building the character before a single frame is generated.
Each principal was developed through detailed character sheets built in Magnific AI and expanded in Runway. Multiple angles, varied compositions, controlled lighting. The sheets became the visual contract for every subsequent generation. Image references and precise prompts guided the video generation. The pipeline held for what the tools could deliver at the time of production.
Reflections
The tools didn’t replace anyone. They enabled something that had no other path to existence. Traditional production requires location, set, crew, actors, production design. Those resources would have kept this vision unrealized indefinitely.
The question isn’t replacement. It’s what becomes possible when the barriers to execution disappear.
