10 Sci-Fi Movies Desperately Needing a Sequel

10. Underwater (2020): Deep Sea Horror Deserves a Return

Underwater, starring Kristen Stewart, perfectly blends sci-fi and horror. It takes place in the Mariana Trench, an incredibly terrifying setting for building suspense; resulting in an experience that both thrills and terrifies. Its monster designs are truly exceptional; and these creatures' introduction really elevates the movie and sets it apart. It really made for something exceptional; a truly exceptional and truly frightening film.

Though the ending might seem conclusive; there's actually a surprising number of other mysteries. Those additional elements hint at potential sequels focusing on that incredibly unique and truly scary undersea environment; showing just how easily something might have gotten improved; providing an expansion onto its core narrative that had otherwise been underused!

9. Edge of Tomorrow (2014): Tom Cruise and Time Loops!

Tom Cruise and Emily Blunt totally slayed in edge of tomorrow, this amazingly creative sci-fi action flick brilliantly plays with time-loop mechanics – it’s Groundhog Day meets alien invasion! That premise and execution were incredibly successful, becoming a very well-made action movie, something still enjoyed today! Yet even ten years after release and still these whispers of potential sequels keep coming up – showing the popularity of this creative premise alone, although these concepts and related ideas remained unconfirmed as of today.

8. Galaxy Quest (1999): A Sci-Fi Comedy Classic Deserving a Sequel

galaxy quest isn’t your typical sci-fi. It’s hilarious. It lovingly satirizes classic sci-fi tropes and fandom (mostly Star Trek). It succeeded hilariously at doing what some similar-themed material utterly failed at! That tone was spot-on; with Tim Allen, Sigourney Weaver, and the legendary Alan Rickman, just to name a few of the exceptionally talented cast; it demonstrates an impressive comedic balance which perfectly demonstrates exactly just what kind of material could possibly become something hugely successful; a successful gamble by a well-known director. It created many references, a ton of comedic potential!

A sequel, poking fun at current sci-fi trends, seems even funnier now. That satire could completely work!

7. District 9 (2009): A Powerful Social Commentary Waiting for a Return

district 9 isn't your typical Alien invasion tale. The found-footage format and serious social commentary set this sci-fi apart; combining serious commentary which impacts viewers today. Its exploration of xenophobia using a compelling found footage storytelling setup – showing alien refugees stuck in a horrible South African slum— creates strong thematic connections with today’s problems.

A sequel could do so much, building on those strong points using new events; bringing those strong opinions on a renewed context that completely delivers on its premise.

6. Jumper (2008): Hayden Christensen's Teleportation Adventure

Hayden Christensen, starring after those infamous Star Wars prequels got the opportunity to really act once more, delivering this action-packed movie centered around teleportation; making for some bank heists and an action-packed tale; one showing how good the actor truly was, and this specific part shows his strengths which fans may have been unable to appreciate from before. It left viewers craving those additional adventures— making this one of the few exceptions to the rules, showing why sometimes leaving things slightly unfinished could result in a surprisingly larger success rate later.

It could easily expand beyond the novel and build on its action; Steven Gould provided additional materials through Reflex; that ten-year time jump opens that door for a phenomenal sequel.

5. Event Horizon (1997): Sci-Fi Horror Needs to be Revived

Event Horizon blends science fiction with an exceptionally dark, scary horror experience; providing this blend only found in some select works of fiction, which showcases this film's very own uniqueness! It shows just how terrifying outer space really could become. This intense, incredibly haunting tale showcases the disturbing realities in sci-fi horror in a much more extreme light.

It deserves a sequel— expanding those terrifying elements from that initial work of fiction and becoming a new and far improved story compared to its own work; and it might just revive a sorely overlooked genre. The horror fans remain waiting.

4. Alien: Covenant (2017): Completing Ridley Scott’s Trilogy

Ridley Scott's Alien prequels, starting with Prometheus and Alien: Covenant, were supposed to become a trilogy; resulting in another additional and even better story which would become yet another major movie addition into this universe, continuing those themes introduced prior and adding additional plots. This one really deserves further completion, as fans await this planned movie and were let down. Even the more recent movies have positive reviews; that audience interest shows many have the longing to revisit this cinematic universe once again.

3. Cloverfield (2008): Monster Movie Mayhem!

Cloverfield's found-footage monster attack remains iconic; its special blend of unique creative vision that could be repeated and replicated only very specifically; creating intense tension and incredible mystery throughout. It did establish an extensive franchise that went well beyond the main concept; this did expand greatly over its entire run! But that doesn't really mean anything!

That first movie remains without a direct sequel; making the lack of expansion in this specific narrative really apparent. Yet this isn’t all bad news; because sequels focusing on this aspect might not only further strengthen the very foundation; they could further connect many of those other loose narratives found through its sequels.

2. The Creator (2023): A Human-AI Love Story

The Creator, directed by Gareth Edwards, is that surprising sci-fi film delivering intense action sequences. It’s focused on war between humanity and AI but with profound messages surrounding love, acceptance, and compassion. That blend of action, strong story and heartfelt themes was pretty successful and delivered results unlike most of the competition it was introduced into, making a good impression even after only having one initial installment.

A sequel would help solidify those brilliant foundations! We could even follow other characters which weren’t initially involved in that conflict. It’s another major opportunity that must be pursued in order to complete its grand storytelling.

1. The Hitchhiker's Guide to the Galaxy (2005): Cosmic Comedy Ready for a Return!

The Hitchhiker's Guide, based on Douglas Adams' classic work. It was a comedy triumph unlike almost every other competitor, adding unique touches rarely found; a true masterclass which blended comedy with the sheer audacity required in outer-space exploration scenarios. That blend is brilliant. It featured an amazing blend of well-established actors; further establishing the cinematic quality available!

Its sequel? Really, really possible! The books themselves feature several additional chapters and the chance to revive its special charm really has immense creative potential, allowing a great revisitation for this widely praised title.

Conclusion: Sci-Fi Fans, Let's Make Our Voices Heard!

These ten amazing movies proved just how much demand for certain genres and experiences exists today, those incredible storylines which could've greatly benefitted from sequels that never actually came to pass. Even the movies that became unexpectedly massive franchises really could have better explored that creative narrative capacity they originally presented; however these are ultimately out of reach in the cases listed today.

Sequels are not easy; studios make various choices and production can be complicated; those failures aren't necessarily poor planning – they are simply the way the world truly operates! However, it is still worth asking these questions: Is there possibly still unmet demand in this niche that could produce another successful title? Can revisiting these creative themes help in new storytelling which uses what audiences have come to love and expect from a sequel? We believe the answer is definitively yes; there might just be a huge potential waiting, just to be found.
