But the assertion that NASA selected it as the most realistic sci-fi movie is not corroborated by the primary NASA source cited here. That source records a NASA official praising The Martian as a realistic Mars film—not a NASA ranking of movies or a judgment about Gattaca.
What does the headline’s NASA claim actually establish?
A March 2, 2025 Daily Galaxy article presents Gattaca (1997) as a compellingly plausible vision of a society organized around genetic selection. It also invokes NASA experts evaluating films. The materials reviewed here do not identify a NASA ranking document or substantiate an official agency decision naming Gattaca.

The NASA primary source concerns a different film and a narrower kind of judgment. In an April 11, 2017 oral-history interview, NASA official James L. Green described reading the book and script for The Martian, advising its filmmakers, and showing them NASA facilities. In that context, he said, “It is the most realistic Mars movie ever.” The antecedent is The Martian; the statement is Green’s assessment of a Mars movie, not a comparative NASA verdict on science fiction as a whole. NASA Johnson Space Center Oral History Project interview, April 11, 2017.
Consulting on a film, an individual expert’s opinion, and a formal agency ranking are different things. A 2022 Ringer interview with Green underscores that distinction: discussing decisions about whether a film is realistic, he says, “that decision’s not made by me.” The interview describes NASA’s film-consultation process; it is not NASA policy documentation.

Why does Gattaca feel like a plausible future?
Gattaca builds its future around a social premise: genetic information and selection influence who is favored and what opportunities they receive. The premise makes the film’s world feel recognizable because its central tension is not only what technology can do, but how people and institutions might use it to sort, reward, or exclude others.
That is a claim about social plausibility, not proof that the film’s entire future has arrived. The Daily Galaxy’s argument is that the film’s concerns about genetic advantage and discrimination remain relevant. It should be read as an interpretation of the film and its themes, not as evidence that every institution in Gattaca exists in real life.
What does “realistic” mean in science fiction?
Calling a movie realistic can mean several different things, and a film can be convincing on one dimension while taking liberties on another:
- Scientific fidelity: Does the depicted technology or physical behavior follow established knowledge?
- Plausible extrapolation: Does the story extend current ideas in a way that seems possible, even if the technology is not established?
- Social plausibility: Do the imagined norms, incentives, and institutions seem like believable consequences of the premise?
- Who is making the judgment: Is it a filmmaker’s stated intention, an individual scientist’s comment, or an attributable agency finding?
For Gattaca, the relevant case is chiefly social plausibility: how a society might turn genetic selection into a basis for status and opportunity. That is a different question from whether a spaceflight film accurately portrays physics or mission operations.

How The Martian and Ad Astra frame realism differently
The comments about The Martian and Ad Astra illustrate why film-realism claims need their context. Green’s remark about The Martian is an individual NASA official’s praise in an account of his consultation with the filmmakers. Director James Gray, discussing Ad Astra at a Washington Post Live event on September 17, 2019, drew a different distinction: “I would say the word I used was wrong: not ‘realistic.’ I would say ‘plausible.’” He said the team tried to adhere to science where possible and depart from it when necessary. The conversation also included NASA space suit engineer Lindsay Aitchison and lunar scientist Sarah Noble. Washington Post Live transcript, September 17, 2019.
These are not competing entries in a verified NASA ranking. They show that a filmmaker’s aim, an expert’s comment about a specific movie, and an agency’s formal comparative judgment are separate forms of evidence. The sources cited here do not establish a single authoritative score across these films.

Gattaca is a defensible choice if “realistic” means a socially plausible speculative future shaped by genetic selection and unequal opportunity. It is not established as NASA’s choice. The NASA evidence cited here supports Green’s favorable description of The Martian as a Mars movie; it does not verify an official NASA decision naming Gattaca the most realistic science-fiction film.
