33 Best Science Fiction Movies to Watch

Aside from their high entertaintment value, speculative tales take us on imaginative journeys while also challenging us to reflect on the world. Whether you’re into extraterrestrial life or time travel, here are the best sci-fi and fantasy movies to stream.

In a world where mortality has been overcome, people watch in awe as the as the 118-year-old Nemo Nobody, the last mortal on Earth, nears his end. He is interviewed about his life, recounting it at three points in time: as a 9-year-old after his parents divorced, when he first fell in love at 15, and as an adult at 34. The three stories seemingly contradict each other. Utilizing non-linear cinematography, Belgian director Jaco Van Dormael presents each of these branching pathways as a version of what could have been. The result is a complex, entangled narrative. That and the movie's ensemble cast, featuring Jared Leto, Sarah Polley, and Diane Kruger, have turned Mr. Nobody into a cult classic. The soundtrack, featuring several of the beautifully restrained music by Eric Satie, is also considered a masterpiece. While it is surely not for everybody, this is trippy, intimate, and existential sci-fi at its best.
Ex Machina is the directorial debut of Alex Garland, the writer of 28 Days Later (and 28 Weeks Later). It tells the story of Caleb (Domhnall Gleeson from About Time), an IT developer who is invited by a billionaire CEO to participate in a groundbreaking experiment—administering a Turing test to a humanoid robot called Ava (Alicia Vikander). Meeting the robot with feelings of superiority at first, questions of trust and ethics soon collide with the protagonist's personal views. While this dazzling film does not rely on them, the visual effects and the overall look-feel of Ex Machina are absolutely stunning and were rightly picked for an Academy Award. They make Ex Machina feel just as casually futuristic as the equally stylish Her and, like Joaquin Phoenix, Gleeson aka Caleb must confront the feelings he develops towards a machine, despite his full awareness that 'she' is just that. This is possibly as close to Kubrick as anyone got in the 21st century. Ex Machina is clever, thrilling, and packed with engaging ideas.

This film really satisfied my craving for an original thriller, despite the fact that I spent most of it thinking about how Logan Marshall-Green looks like a budget Tom Hardy.

He plays a guy whose wife is killed during a violent mugging that also leaves him paralyzed in the aftermath. When a billionaire approaches him with an Artificial Intelligence solution that would "upgrade" his body, he has a chance to take vengeance.

This is Robocop meets Ex Machina meets Blade Runner. It's original, low-budget without feeling low-budget, and honestly just so thrilling. It gives the genre of sci-fi a much needed upgrade.

Moon is a sci-fi movie that doesn’t care that it’s a sci-fi movie. It’s not about space exploration or aliens. It’s about a man struggling to understand what and who he is and the dehumanizing effect of industrialization. Moon leaves you with a pit in your stomach and an incredible feeling of melancholy. It is perfectly acted by Sam Rockwell and the voice of Kevin Spacey. Moon keeps you guessing and deeply enthralled. A true masterpiece I would recommend to anyone, whether they are sci-fi nerds or just movie lovers.

In the year of the Netflix TV Show Maniac, another absurdist title stole critics’ hearts. Sorry to Bother You is a movie set in an alternate reality, where capitalism and greed are accentuated. Lakeith Stanfield (Atlanta) is a guy called Cassius who struggles to pay his bills. However, when at a tele-marketing job an old-timer tells him to use a “white voice”, he starts moving up the ranks of his bizarre society. A really smart movie that will be mostly enjoyed by those who watch it for its entertaining value, and not so much for its commentary. It is like a Black Mirror episode stretched into a movie.

In a very fun thriller format, this show is about three eccentric comic book fans who come across a graphic novel that has information on future world events, like epidemics.

Also looking for this novel are a couple of violent hitmen from an organization called “The Network”. The three youngsters find themselves up against a dark web of conspiracies and violence.

It’s plot-heavy, imaginative, and very enjoyable - everything you’d expect from a good thriller series.

Serenity is a futuristic sci-fi film that serves as a feature-length continuation of the story-line from the TV program Firefly (2002-2003). The story revolves around the captain (Nathan Fillion) and crew of the titular space vessel that operate as space outlaws, running cargo and smuggling missions throughout the galaxy. They take on a mysterious young psychic girl and her brother, the girl carrying secrets detrimental to the intergalactic government, and soon find themselves being hunted by a nefarious assassin (Chiwetel Ejiofor). The first feature-length film from Joss Whedon (The Avengers), Serenity is a lively and enjoyable adventure, replete with large-scale action sequences, strong characterizations and just the right touch of wry humor. An enjoyable viewing experience that stands alone without demanding that you have familiarity with the original program beforehand.

The movie starts with Professor John Oldman packing his things to leave and start a new life. He invites his friends to say goodbye and decides to reveal the reason for his departure. The starting point of the narration is a simple question asked by Oldman to his friends: what would a man from the upper paleolithic look like if he had survived until the present day? As scientists, the protagonists play his game and investigate the question, not knowing whether the story is a bad joke or a genuine narration. One of the best movies I've watched and definitely one of the most under-rated.

One of the most original time-travel thrillers since 12 Monkeys. A brilliant subversion of the Time Paradox trope, with enough plot twists to keep you entertained until well after the movie is finished. Predestination is an amazing movie with great performances from Ethan Hawke and Sarah Snook. It's a movie that will feel like Inception, when it comes to messing with your mind and barely anyone has heard of it. It is highly underrated and unknown, sadly.

Director Bong Joon-ho (Snowpiercer) does something quite amazing with the $50 million budget Netflix gave him: he makes a simplistic movie. But man, is it good. Okja tells the story of a “super pig” experiment that sends genetically modified pigs to top farmers around the world. In Korea, a farmer’s granddaughter forms a special relationship with one of these super pigs (Okja). When the company who originally ran the experiment want their pig back (performances by Jake Gyllenhaal and Tilda Swinton) – the two find an ally in an animal advocacy group led by Jay (Paul Dano). This is a straightforward movie, but nevertheless it is entertaining and full of thought-provoking themes and performances from an excellent cast.

Snowpiercer is an under-the-rader post-apocalyptic thriller that offers the grittiness that many times only Asian cinema may achieve. South Korean director Joon-ho Bong forces audiences to forget that Chris Evans was ever a Marvel superhero, as he leads a revolt of his fellow “low-class” citizens against the self-appointed gentry in a train that contains all remaining members of the planet. With immersive environments and a layered script, this film melds together social commentary and moral discourse in a visually arresting and vastly entertaining package.

Andy Samberg, Cristin Milioti (Modern Love, Black Mirror), and J.K. Simmons star in this easy but original rom-com that takes place in a wedding time loop. Nyles (Samberg) finds himself living the same day over and over again, so he gives in to the monotony and the fact that there is no way to escape it. 

When he is about to hook up with one of the guests, Sarah (Milioti), he is attacked by a mysterious character. The routine of his time-loop is broken. 

Palm Springs is often surreal and philosophical, which are not adjectives usually used to describe rom-coms. It offers just enough twists to be original without jeopardizing the things that make it a good rom-com.

A quirky little movie about a reporter trying to get a story about a man who posted an ad looking for someone to travel in time with. The movie's main strength is the fantastic casting of talents that usually live in the series world (Jake M. Johnson from New Girl, Aubery Plaza from Parcs and Recreation, Mark Duplass), and although it might seem a little bit slow at the beginning, it is worth every second spent watching it.
