7 Best British Sci-Fi Movies Of All Time, Ranked

Over the years, British filmmakers and studios have created some of the most famous and successful science fiction movies ever made. The UK has long been a leader in the sci-fi genre, producing imaginative stories about space travel, zombies, post-apocalyptic worlds, artificial intelligence, and alien life. Alongside popular British sci-fi TV shows like Doctor Who, Years and Years, Utopia, Misfits, 3 Body Problem, and Supacell, British science fiction consistently captivates movie audiences as well.

Britain has produced many fantastic science fiction films, and we’ve chosen seven that are particularly noteworthy for their impact, emotional depth, strong storytelling, and lasting influence. These films come from celebrated directors like Terry Gilliam, Danny Boyle, Alex Garland, Alfonso Cuarón, and Stanley Kubrick, all well-known for their work in the sci-fi genre. While British sci-fi continues to evolve with films like Ridley Scott’s The Dog Stars and Jonny Campbell’s Cold Storage, these seven movies remain benchmarks for quality.

7) Attack the Block (2011)

Joe Cornish made his directorial debut with Attack the Block, and it also launched John Boyega’s acting career. While Boyega has since become famous in films like Star Wars, They Cloned Tyrone, and The Woman King, many still consider Attack the Block to be one of his best roles. Released in 2011, this British sci-fi comedy horror didn’t perform well at the box office, but it earned widespread critical acclaim and has become a beloved cult classic. The film follows a teenage street gang in South London as they defend their neighborhood from an alien invasion, and it’s known for being exciting, surprising, original, and visually striking.

6) Brazil (1985)

Terry Gilliam, known for his work with Monty Python, created Brazil, a film that wasn’t a hit in the US but became popular in the UK in 1985. The movie portrays a darkly humorous and critical vision of a future society overwhelmed by broken-down technology. Featuring a talented cast including Jonathan Pryce, Robert De Niro, and Michael Palin, Brazil is a clever and thought-provoking political satire and fantastical story often considered one of the greatest British films ever made.

5) 28 Days Later (2002)

While some people see zombie and sci-fi movies as separate, the beginning of 28 Days Later – which shows the virus that causes the outbreak was created in a lab – firmly places it in the science fiction category. Written by Alex Garland and directed by Danny Boyle, it was their first collaboration and quickly became a game-changer in the genre, launching Cillian Murphy’s career. The film’s simple but effective story is considered by many to be one of the greatest movies ever made, and a standout in British cinema. Its subtle tension, thrilling action, creative visuals, and smart use of locations make 28 Days Later a truly unforgettable and important film.

4) Children of Men (2006)

Directed by Alfonso Cuarón, known for films like Gravity and Roma, the 2006 movie Children of Men is based on P.D. James’ 1992 novel of the same name. The film is highly praised and often considered one of the greatest ever made. It depicts a future where humanity faces extinction after twenty years of infertility. Theo Faron (Clive Owen) must protect Kee (Clare-Hope Ashitey), a woman who is miraculously pregnant, and get her to safety. Cuarón uses extended, unbroken shots to pull viewers into the film’s intense and chaotic world, making it feel strikingly realistic. With its high production quality, compelling acting, smart writing, and innovative visuals, Children of Men is a truly unforgettable cinematic experience.

3) Moon (2009)

Duncan Jones’ 2009 film, Moon, quickly gained attention after its debut at the Sundance Film Festival. The movie tells a realistic and thought-provoking story about a man, Sam Bell (played brilliantly by Sam Rockwell), working alone on the Moon to mine helium-3. His solitary mission takes a dramatic turn when he uncovers shocking truths about his employer. As Jones’ first feature film, Moon is a remarkably well-made science fiction story that thoughtfully explores what it means to be human, all with a small cast and a focused narrative. It’s a standout example of British science fiction cinema.

2) Ex Machina (2014)

While Alex Garland previously wrote the screenplay for 28 Days Later, he’s since become a highly respected director known for thought-provoking science fiction. He’s created impressive projects like Annihilation, Men, and Devs, but his first film, Ex Machina, remains his most powerful work. The movie follows Caleb (Domhnall Gleeson) who is invited to the secluded home of tech CEO Nathan Bateman (Oscar Isaac) to evaluate Ava (Alicia Vikander), a remarkably human-like artificial intelligence. Ex Machina is a subtly moving and suspenseful film, full of surprising turns and a compelling exploration of what it means to be human in an age of advanced technology and AI – and it’s often considered one of the best sci-fi films ever made.

1) 2001: A Space Odyssey (1968)

2001: A Space Odyssey is one of the most important and well-known science fiction films ever made. While director Stanley Kubrick was American, the movie was a British-American collaboration, filmed and largely created in the UK, making a strong case for it being the greatest British sci-fi film. The story centers on a group of astronauts and scientists traveling to Jupiter to explore a strange alien object, a monolith, and was co-written by the famous British science fiction author Arthur C. Clarke, drawing inspiration from his short stories.

With its incredible visuals, limited use of dialogue, and thought-provoking ideas about technology, artificial intelligence, and extraterrestrial life, 2001: A Space Odyssey set the bar for science fiction films that followed. Widely considered one of the most important and influential movies ever made, it rightfully earns the number one position on this list.
