Best Sci-Fi Movies 2026 - Ranked, Streaming Now & Arriving Through December

Project Hail Mary

Andy Weir's novel is one of the best science fiction books of the 21st century - a piece of hard sci-fi that works as a thriller, as a character study, as a meditation on what it means to be human in the face of something vast and indifferent, and as one of the most surprising and emotionally affecting stories the genre has produced in years. The central relationship at the heart of the novel is unlike anything else in science fiction.

Phil Lord and Christopher Miller - the directors who made The Lego Movie, 21 Jump Street, and Spider-Man: Into the Spider-Verse - are exactly the right people to adapt it. They understand how to make an audience feel things they didn't expect to feel, using tonal combinations that should not work and somehow, in their hands, always do. Ryan Gosling brings exactly the combination of intelligence, physical presence, and emotional vulnerability that Ryland Grace demands.

If this film lands the way the source material deserves - and every signal suggests it will - it will be the defining sci-fi film of 2026 by a distance so large it isn't worth discussing the competition.

Read the book before you see the film if you can. Not because the film will spoil it - but because experiencing Weir's prose and then Lord and Miller's interpretation of that same story are two completely distinct pleasures, and you want both. If you can't read it first, go in as cold as possible and avoid all trailers beyond the first one.

Dune: Part Three

Denis Villeneuve completes what will be remembered as one of the great literary adaptations in cinema history. Part One rebuilt Herbert's world from the ground up - patient, vast, deliberately disorienting in all the right ways. Part Two delivered on everything Part One promised, and more. Part Three carries the full weight of the Messiah arc: the corruption of prophecy, the terrible logic of religious war, the personal cost of becoming something larger than human.

Villeneuve has earned the right to close this trilogy on his own terms. After two films of extraordinary visual and emotional scale, Part Three arrives as not just the conclusion of a story but the culmination of a directorial vision that has been building for six years. This is the cinematic event of December 2026 - and possibly of the entire year.

Watch Part One and Part Two again before December. Block out a weekend. Take notes if the politics of the universe have blurred since you last saw them. The finale will reward preparation and punish inattention.

The Odyssey

Christopher Nolan adapting Homer's Odyssey is the kind of announcement that reframes what cinema can aspire to. After Oppenheimer proved - definitively - that films of genuine intellectual and emotional scale can also be the highest-grossing films in the world, Nolan arrives with the most ambitious project of his career: a 3000-year-old epic poem, rendered in IMAX, with a cast and production scope that matches the source material's claim on human imagination.

The Odyssey sits at the intersection of mythology and science fiction in a way that Nolan's interest in time, consciousness, and the mechanics of narrative makes him uniquely suited to explore. What he does with Odysseus's journey - a man trying to get home across a world that keeps presenting him with new reasons to stay - is one of the most anticipated questions in 2026 cinema.

This is not background viewing. Block out the time. Go to the largest screen you can find. Turn your phone off before you sit down, not after the lights go down. Experience it as it was built to be experienced.

The Mandalorian & Grogu

The first Star Wars theatrical film in years, and the one with the clearest emotional foundation going in. The Mandalorian series built genuine affection for its characters in a way that the sequel trilogy never quite managed - the relationship between Din Djarin and Grogu became one of the most universally beloved things Star Wars has produced since the original trilogy.

Moving that relationship to the big screen, with a theatrical budget and the directorial craft that Jon Favreau and Dave Filoni have developed over three series seasons, is a proposition that the audience is already emotionally invested in before a single frame is shown. That investment is both the film's greatest asset and its most significant challenge.

Watch The Mandalorian Seasons 1–3 first if you haven't already. The emotional weight of the film will be significantly greater for having that context. The series is excellent on its own terms - the film rewards it.

Avengers: Doomsday

The biggest Marvel event since Endgame. Doomsday arrives in December as the convergence point for everything the post-Endgame MCU has been building - the introduction of the multiverse, the establishment of new heroes, the careful seeding of Doctor Doom as an antagonist who operates on an entirely different ideological register than Thanos. Where Thanos wanted to reduce the universe, Doom wants to control and perfect it. That distinction makes him one of the most interesting villains Marvel has ever had access to.

The Russo brothers returning to direct - the team behind The Winter Soldier, Civil War, Infinity War, and Endgame - is the single most reassuring signal the production could have sent. Their instinct is for scale, consequence, and the kind of procedural thriller tension that transforms superhero cinema into something with genuine dramatic weight.

If you've been drifting in and out of the MCU since Endgame, now is the time to re-engage. The key threads to follow: the multiverse variants, the Fantastic Four introduction, and the post-Secret Wars landscape. The Russos will make it navigable - but familiarity with the recent world-building pays dividends.

Spider-Man: Brand New Day

No Way Home ended with one of the boldest creative decisions in modern superhero cinema - a reset that cost the character everything the audience was invested in, in exchange for a clean slate and the creative freedom to tell a new Spider-Man story. Brand New Day is named after the comics arc that solved precisely this problem in print, and the question of whether the film finds an equivalent cinematic solution is one of the most interesting creative puzzles of 2026.

Tom Holland has grown significantly as a performer since the early films - the emotional depth he brought to No Way Home's final act suggested a Spider-Man film where the science fiction stakes and the human costs exist in genuine balance, rather than one always subordinating the other.

No Way Home is essential preparation - one of the best superhero films of the last decade and the direct emotional setup for everything Brand New Day is built around. If you haven't seen it recently, rewatch it before this arrives.

The Super Mario Galaxy Movie

Following the billion-dollar success of The Super Mario Bros. Movie in 2023, Nintendo and Illumination return with the Galaxy-spanning adventure - and the visual ambition of the premise is immediately apparent. Galaxy takes Mario into the cosmos: spinning planetoids, gravitational anomalies, vast space environments that would have been impossible to realise in the 2D era of the games and that now, on a cinema screen with a full animation budget, have the potential to be spectacular.

The first film was significantly better than expectations - charming, technically accomplished, and committed to the pleasures of the source material without condescending to them. The sequel has those foundations to build on.

The first Mario film is an excellent pre-watch, but not required. Galaxy introduces enough new concepts and settings that it works cleanly as a standalone. Take whoever you'd take to a Pixar film.

Masters of the Universe

He-Man arrives in live-action on a proper budget for the first time since the baffling 1987 Dolph Lundgren film, and the premise has things going for it that the original never did: Eternia as a world where medieval swords coexist with alien technology and a cosmology of genuine mythological scale. Kyle Allen plays He-Man/Prince Adam. The challenge the film faces is the same one every Masters adaptation faces - the source material has enormous affection attached to it and enormous camp potential, and navigating between them without losing either requires real creative confidence. Early word is cautiously positive.

Expectations calibration matters here. This is big-budget franchise cinema built for a wide audience, not a prestige sci-fi event. If it gets the balance right, it could be the most purely enjoyable franchise reboot of the summer. If it tips too far into camp, the fanbase will not be forgiving about it.

Mortal Kombat II

The sequel to 2021's reboot arrives with a larger budget, a more confident mythology, and the creative accountability that comes from knowing exactly what the first film's audience responded to. The Mortal Kombat universe is, at its core, a science fiction premise - interdimensional tournament combat, realm-spanning politics, a cosmology of worlds with their own rules and powers. The sequel has the opportunity to expand that cosmology in ways the first film only gestured toward.

Watch the first Mortal Kombat reboot before this - the world-building it establishes is foundational to the sequel's stakes. If you bounced off it on first viewing, the action sequences alone justify a second attempt.

Disclosure Day

A government analyst discovers a classified programme - officially shuttered fifteen years ago - is still running. The closer she gets to what it actually is, the more people appear to already know she's looking. For sci-fi fans, the territory is immediately recognisable: institutions that conceal the shape of reality, the question of what governments choose to protect from public knowledge, the vertigo of discovering the world is structured differently from what you were told. Disclosure Day takes those premises and builds a procedural thriller around them that earns its paranoia through specificity rather than gesture.

For fans of Contact, Arrival, and Enemy of the State - the intersection of institutional paranoia and the question of what we are actually told about the world we live in.

Sinners

Ryan Coogler's supernatural thriller set in 1930s Mississippi - twin brothers returning home to find something ancient and deeply wrong - operates in a register that serious sci-fi fans will recognise immediately: the collision of the explainable and the inexplicable, the question of what exists in the world that human categories cannot contain. Coogler's visual intelligence and his understanding of how mythology and history intersect make Sinners one of the most distinctive films of 2026 in any genre.

Go in with as little information as possible. Sinners is a film that rewards not knowing what kind of film it is - let it reveal itself on its own terms. The less you've read, the more effective it is.
