10 Sci-Fi Films With More Science Than Fiction

If you like your science fiction grounded in real science rather than Marvel-style spectacle, these are the films the scientific community itself rates highest. Every wild idea in them is built on actual physics, biology, or astronomy — and the list focuses on the last 30 years, with a single exception from 1971.

Gattaca (1997) — a world where your genes decide your social status; the genetic engineering is far ahead of reality, but the way it works is shown faithfully for its time.
Her (2013) — a man falls in love with his voice assistant. A fantasy? Less and less every year.
Deep Impact (1998) — scientists call it the best blend of solid science, spectacle, and drama in a disaster film: a realistically sized 11-kilometre comet and a believable timeline from discovery to impact.
Interstellar (2014) — wormholes and time dilation may sound impossible, but they rest on real theoretical physics, and the black hole was visualised with the help of Nobel-winning physicist Kip Thorne.
Contact (1997) — the SETI Institute is portrayed faithfully, and the aliens communicate through mathematics, just as scientists expect they would. NASA ranked it the second most scientifically accurate sci-fi film ever made.
The Martian (2015) — the eight-month flight, growing potatoes, dust devils, and a spacesuit based on real NASA designs; the inaccuracies are mostly cosmetic.
Minority Report (2002) — predicting crimes before they happen is still fiction, but the film’s retina scanners, motion-tracking interfaces, and targeted advertising have all since become real.
Moon (2009) — a slow, low-budget gem about a lone miner harvesting helium-3 on the Moon, with an AI voice assistant that now feels like a prophecy. The whole film cost just $5 million.
Arrival (2016) — the filmmakers built a complete alien language with the help of linguists and phonetics experts, which is what sets it apart from films that wave away the language problem.
The Andromeda Strain (1971) — the one older exception: a military satellite crashes in a small American town, spreading a deadly virus that kills everyone but a baby and an old man. A 2003 paper called it the most scientifically accurate killer-virus film ever made.
