10 Greatest Sci-Fi Movies With The Best Worldbuilding

Many of the greatest and most memorable movies of all time whisk audiences into a world more wondrous than our own. Even if those locations are scary or dangerous, the best worlds feel lived in, and often beg for expansion either in sequels or fan theories. In some titles, those worlds are so important to their movies that they feel like characters of their own.

You can find titles with impressive worldbuilding in many genres, though few are as intrinsically linked as sci-fi. Science fiction movies explore everything from time travel and futurescapes to strange alien worlds. Many titles use those worlds as a platform for their stories, while in others, they are just as important as any plot or actor.

We're looking at some of the greatest worlds ever committed to film in this list. Many of these movies are sci-fi epics, or critically adored darlings of the industry. Others offer unique takes on the future, whether it's a gritty portrayal of a world we wouldn't want to live in, or a hopeful glimpse of what could be.

The future of Earth is always a fascinating concept to explore, but many of the best worldbuilding takes place on distant planets or in realms only loosely connected to our own. Whether you're looking for a movie with a gorgeous alien world to draw you into, or a galaxy with its fate decided by a family feud, here's a selection of great sci-fi movies with incredible worldbuilding.

10 Demolition Man (1993)

Demolition Man was arguably ahead of its time, depicting a safe but oddly sterile world where everything is policed. Swearing is outlawed, and the general populace is so compliant that violent crime is seemingly eradicated.

It may sound like a perfect future to some, though chaos ensues when a once cryogenically frozen criminal, Simon Phoenix (Wesley Snipes), wakes up. The city is no longer equipped for his 90s brand of lethality. Authorities are forced to thaw John Spartan (Sylvester Stallone), a hardened cop of the era, to deal with him.

Demolition Man depicts a remarkable future with conflict bubbling under the surface. It's grounded enough to remain believable, and fans are still theorizing about "the three shells" to this day.

9 The Fifth Element (1997)

The Fifth Element is a classic 1990s sci-fi action movie starring Bruce Willis as Korben Dallas. He's a cab driver, thrust into a quest to save the world from an ancient evil. The movie boasts an unforgettable cast, including Milla Jovovich, Chris Tucker, and Gary Oldman as the wonderfully evil Zorg.

The movie offers a superb, family-friendly sci-fi adventure, and it also offers a surprisingly upbeat portrayal of the future. Flying cars are now the norm, as is space travel to paradise planets.

The Fifth Element hints at so many small details that make the world feel alive. For example, Korben is trying to quit smoking, and a machine allots him cigarettes where most of the stick is a filter. There's also a device that seemingly makes mouthwatering food to order in an instant. It's a beloved movie, and among Luc Besson's best.

8 Serenity (2005)

Serenity may be a cheeky entry because the lore is fleshed out by the Firefly TV series that came before the feature film. Nevertheless, the movie contains a superb standalone story about Malcolm Reynolds (Nathan Fillion) and the crew of his Firefly-class spacecraft, Serenity.

The universe of Serenity has many moving parts, but the movie introduces us to the Alliance, a wealthy, high-tech group, and the Brown Coats, resistance fighters who lost a war between the two factions. The galaxy is full of conflict, though everyone fears the Reavers, who are cannibalistic and do unspeakable things to their victims.

Serenity makes the list because it's such a feature-rich movie that it encouraged many newcomers to check out the show. The Brown Coats also boast a distinct style that blends sci-fi with Western fashion.

7 Dark City (1998)

Dark City is an incredibly atmospheric neo-noir sci-fi title with a fascinating world. The movie stars Rufus Sewell as Murdoch. He wakes up in a bathtub in an old-fashioned hotel with no clue how he got there or who he is.

Part of what makes Dark City so intriguing is the slow-burn mystery that unfolds, which I won't spoil here. The movie is set in a city where dawn seemingly never comes. Murdoch is wanted for murders he has no recollection of, and citizens appear to fall asleep at the same time each night.

Dark City features a great cast and mysterious tall pale figures with otherworldly powers. The world features a strange mix of buildings from different time periods, as a grand sci-fi tale unfolds.

6 Dune (2021)

Dune tells a multilayered story set on the unforgiving desert planet of Arrakis. The movie is based on the novel of the same name, starring Timothée Chalamet as Paul Atreides in a story of honor, houses, and betrayal on a grand scale.

One of the greatest draws of Dune is Arrakis itself. The planet is the only known source of spice. It is one of the most valuable commodities in the universe, extending human life. It also enhances mental abilities, enabling space travel that would be impossible without it.

Dune takes time to explore life and politics on Arrakis, and the relationship between houses and the emperor. The 2021 movie is the first part of a much grander story, but sows enough intriguing seeds to hold audiences for its entire two and a half hour runtime.

5 The Matrix (1999)

The Matrix boasts incredible worldbuilding as it presents our own world as something entirely different. Our world is a simulation the vast majority of people are plugged into. The real world outside the simulation may have futuristic technology, but it's far less inviting, as humans are losing a war against the machines.

Keanu Reeves stars as Neo, who has just been unplugged from the Matrix. Our heroes can bend the rules of the Matrix somewhat and can even dodge bullets. However, there are sentient programs called Agents who can do the same and more with lethal efficiency.

The scope of The Matrix lore is vastly expanded in the sequels, focusing more on human life outside the simulation. It's a surprisingly desperate sci-fi world behind the curtain, even if Neo and Trinity (Carrie-Anne Moss) look absurdly cool in the simulated world.

4 Avatar (2009)

Avatar may be a low-hanging fruit, but Pandora is a fascinating planet and the films worldbuilding is truly exceptional. The movie tells a straightforward story about humans invading Pandora to mine a priceless mineral called unobtainium.

Naturally, this angers the Na'vi, the species inhabiting the planet. A human named Jake Sully (Sam Worthington) assumes control of a Na'vi Avatar, and quickly defects from his military duties as he learns more about the planet and its inhabitants.

It almost seems unfair to add Avatar to the list, because the movie spends so much of its two hours 40 minutes' runtime showing audiences the sights. The title feels like a tour of the planet, something the sequels also accomplish and build on.

3 Blade Runner (1982)

Blade Runner is set in a dystopian sci-fi future, starring Harrison Ford as Deckard. He's a Blade Runner, a special agent trained to kill rogue replicants, who are manufactured, artificially created beings. They aren't typical robots, which makes the movie stand apart from similar titles.

Interestingly, Blade Runner is set in 2019, which makes its depiction of the time period so alluring. The future is dark and dirty, and the city feels lived-in and dangerous. There are many different sorts of architecture, alongside giant ad boards and flying cars.

It's almost always raining in Blade Runner, and the movie tells a slow-burning story, taking plenty of time to show audiences the sights. Blade Runner 2049 also does an admirable job of expanding the world while staying faithful to the original.

2 Aliens (1986)

Ridley Scott's Alien introduced audiences to one of the most terrifying creatures in movie history in 1979. The sequel, Aliens, brought Ellen Ripley (Sigourney Weaver) back into the fray and expanded the lore in arguably one of the greatest sci-fi action movies ever made.

The xenomorph was already a horrifying creature, and Aliens shows how even highly trained soldiers are powerless against such a threat. The movie paints a bleak picture of corporate greed in the face of an existential threat as we see the xenomorphs decimate an off world colony.

Technology is oddly alluring in Aliens because much of it looks old by today's standards. It looks gritty and worn, and it's an aesthetic used throughout the entire movie. An iconic cast also supports Ripley, responsible for numerous one-liners that remain a part of pop culture.

1 Star Wars: Episode IV - A New Hope (1977)

Star Wars: Episode IV - A New Hope was the first movie in the cultural phenomenon that's still going strong today. It's a timeless sci-fi adventure that showed enough of its universe in a single movie to blow audiences away, with plenty of room to expand on events before and after.

A New Hope introduced so many elements of its rich galaxy at such a rapid pace that it's easy to take that near-perfect execution for granted. We're introduced to Luke Skywalker (Mark Hamill) on his home planet of Tatooine. The movie quickly moves to the Mos Eisley Cantina, then into space aboard the Millennium Falcon with Han Solo (Harrison Ford).

The movie masterfully juggles so many unique aspects, from the Jedi to the Death Star, yet it remains coherent and easy to understand. It's a universe that begs for expansion, and that development is still continuing today in one of the greatest examples of sci-fi worldbuilding in the industry.
