Ridley Scott has been a cinematic force for decades, and while he's known for historical epics like Gladiator and The Last Duel, his science fiction output is arguably his most iconic. From the haunting corridors of the Nostromo to the rain-soaked streets of a future Los Angeles, Scott has shaped the genre like few others. With six sci-fi films under his belt, we've ranked them all, from the essential to the forgettable.
6. The Dog Stars (2026)
Scott's most recent sci-fi effort, The Dog Stars, is a post-apocalyptic slog that squanders a talented cast. Jacob Elordi, Josh Brolin, and Margaret Qualley do their best, but the film is mostly a sleepy hangout movie with occasional bursts of action. One bizarre set piece near the end briefly jolts the narrative, but it's not enough to save a story that feels derivative and dull. If you've seen any post-apocalyptic film in the last decade, you've seen this, and done better. It's a disappointing end to what was otherwise a strong run in the genre.
5. The Martian (2015)
The Martian is a crowd-pleaser, but it's also Scott's safest sci-fi film. Matt Damon plays Mark Watney, an astronaut stranded on Mars, in a survival story that's engaging but never particularly daring. It's a well-made, entertaining film, but it lacks the ambition and visual invention of Scott's best work. The Golden Globe for Best Musical or Comedy was a stretch, but the film's charm and humor are undeniable. It's a solid, if unremarkable, entry in Scott's filmography.
4. Alien: Covenant (2017)
This sequel to Prometheus is divisive, but it's better than its reputation suggests. Alien: Covenant leans into the horror of the original Alien, with a xenomorph causing chaos, but its most interesting elements involve Michael Fassbender's dual performance as androids David and Walter. The film looks stunning, and Fassbender's scenes are genuinely compelling. It's a messy but fascinating entry that deserves more credit than it gets.
3. Prometheus (2012)
Scott's return to the Alien universe was a bold, philosophical take on creation and humanity. Prometheus is ambitious and visually spectacular, with a standout performance from Noomi Rapace. The film's themes are thought-provoking, even if the plot has some holes. It's a flawed but ambitious work that raises questions about our origins and the nature of creation, making it a worthy addition to Scott's sci-fi canon.
2. Blade Runner (1982)
A neo-noir masterpiece, Blade Runner is a visual and thematic triumph. Set in a rain-soaked, neon-lit Los Angeles, the film follows Rick Deckard (Harrison Ford) as he hunts replicants. The film's exploration of what it means to be human, combined with its stunning production design, has made it a touchstone of the genre. It's a slow-burn, but its influence is immeasurable, and it remains one of the greatest sci-fi films ever made.
1. Alien (1979)
There's no contest: Alien is Ridley Scott's best sci-fi film. It's a masterclass in tension and horror, with a terrifying creature design by H.R. Giger and a breakout performance from Sigourney Weaver as Ellen Ripley. The film's claustrophobic atmosphere and relentless suspense make it a timeless classic. It's not just a great sci-fi movie; it's one of the greatest films of all time. For more on the genre, check out our list of the best sci-fi TV shows of the 21st century.
Scott's sci-fi filmography is a mixed bag, but when he's at his best, he's unmatched. From the terror of Alien to the philosophical musings of Prometheus, his films have left an indelible mark on cinema. While The Dog Stars may be a low point, it doesn't diminish the legacy of his genre-defining work. For more on Scott's recent controversies, see his response to critics.
