Few things in cinema are more frustrating than a great movie that ends with unanswered questions, untapped potential, or characters that just beg to return to the screen. Hollywood loves a sequel, but sometimes, incredible films fall through the cracks, leaving fans to wonder what could have been.

Here, we’re taking a nostalgic look back at ten movies that deserve a sequel but, for some reason, never got one. Whether it’s an unresolved cliffhanger, a rich universe begging for expansion, or characters we simply can’t get enough of, these films had “sequel” written all over them.

Grab your popcorn as we spotlight the movies that made us hope, dream, and maybe even beg for a Part 2.

1. The Iron Giant (1999)

Despite being a box-office underdog at the time, The Iron Giant has grown into a beloved classic over the years. The heartfelt story of a young boy, Hogarth, and his friendship with a massive, otherworldly robot captured the imagination of viewers of all ages. The film’s bittersweet ending—which sees the Giant sacrificing himself to save humanity, only to hint at his survival in the final scene—is perfect sequel material.

A follow-up could explore where the Giant ends up, how Hogarth copes as he grows up, and whether humanity can fully accept the Iron Giant. With its themes of friendship, sacrifice, and acceptance, there’s enough material here for an emotional and thrilling second chapter.

Why it deserves a sequel: Unanswered questions about the Giant’s future and the powerful connection between Hogarth and his robotic companion.

2. District 9 (2009)

Neill Blomkamp’s District 9 is an innovative sci-fi movie that blends allegory with stunning visuals. The film follows Wikus, a human-turned-alien hybrid, who promises a return from the alien mothership in three years. The story ends on a cliffhanger, leaving audiences desperate to know what happens to Wikus, the oppressed “prawns,” and Earth itself.

Fans have been campaigning for a sequel for years as the rich, world-building elements practically beg for further exploration. Blomkamp has teased the idea of District 10, but over a decade later, we’re still waiting.

Why it deserves a sequel: A gripping unresolved storyline and a thought-provoking universe with endless possibilities.

3. The Goonies (1985)

This cult classic about a group of misfit kids hunting for pirate treasure has been adored for generations. The Goonies is a nostalgic gem, blending adventure, humor, and teamwork in a way that hasn’t aged one bit. But imagine seeing the next generation of Goonies!

A sequel could follow the original cast as adults, embarking on another treasure-hunting escapade with their kids. Or perhaps, it could feature an entirely new crew of adventurers inspired by the original Goonies. Either way, another dose of “Goonies never say die!” magic would be worth the wait.

Why it deserves a sequel: The lovable characters, the timeless adventure, and endless potential to reignite the charm with a new generation.

4. Alita: Battle Angel (2019)

Fans pleaded for this adaptation of Yukito Kishiro’s manga to get a sequel the moment the credits rolled. Alita introduces us to a world packed with rich lore, high-energy action, and a compelling protagonist seeking to uncover her past.

With Alita’s quest to confront Nova and learn the truth about her origins far from fulfilled, a follow-up feels natural. Not to mention the film’s stunning visuals, which practically beg for another outing on the big screen.

Why it deserves a sequel: Alita’s origins and destiny remain unexplored, leaving so much room for story expansion.

5. Inception (2010)

Christopher Nolan’s Inception is a mind-bending masterpiece that had fans analyzing every frame. The ambiguous ending, with Cobb’s spinning totem, has sparked debates for over a decade. Did it fall? Did Cobb finally reunite with his kids?

While there’s something perfect about how the movie leaves us questioning, a sequel could explore new dreamscapes, inventive heists, or even follow a fresh team manipulating the subconscious. The potential for another deep-dive into Nolan’s carefully constructed dream worlds is endless.

Why it deserves a sequel: The cliffhanger ending and the limitless possibilities of dream technology.

6. Dredd (2012)

This visually striking and action-packed reboot of Judge Dredd wasn’t a blockbuster hit, but it gained a cult following. Karl Urban’s sharp portrayal of the titular character and the gritty Neo-futuristic setting made us crave another round of justice in Mega-City One. Fans have been vocal, even launching petitions for a sequel or spin-off series.

A sequel could further explore Dredd’s world, introduce more comic lore, or push into even darker territory. With Urban eager to reprise the role, hope still lingers.

Why it deserves a sequel: A gritty, richly established universe with endless storytelling potential and a lead actor ready to return.

7. The Nice Guys (2016)

Ryan Gosling and Russell Crowe proved to be an unexpectedly hilarious duo in The Nice Guys. Shane Black’s buddy comedy/thriller captured hearts with its witty script, sharp humor, and undeniable chemistry between its leads.

A follow-up could place the bumbling duo in another wild, convoluted case. With Gosling’s knack for comedy and Crowe’s deadpan delivery, the possibilities for another round of antics are endless.

Why it deserves a sequel: Unmatched chemistry and a story world ripe for another quirky caper.

8. Sky High (2005)

This superhero-themed high school movie struck a delightful balance between heart, humor, and action. Following a group of students learning to harness their powers, Sky High was ahead of its time in blending coming-of-age themes with comic book action.

A sequel could follow the original characters as young adults grappling with the realities of heroism, or introduce a new generation of students at Sky High. With superhero movies dominating pop culture, now feels like the perfect time to revisit this unique premise.

Why it deserves a sequel: Its fresh take on superheroes and the nostalgia surrounding its lovable characters.

9. Serenity (2005)

Based on the much-loved but short-lived series Firefly, Joss Whedon’s Serenity managed to provide some closure after the show’s untimely cancellation. However, its passionate fanbase still feels the sting of unresolved questions and underexplored storylines.

A sequel could explore the aftermath of the Reaver attack, more of River Tam’s incredible powers, or a new adventure with the Serenity crew. With diehard fans still keeping the Firefly flame alive, the film’s universe is just too rich to leave dormant.

Why it deserves a sequel: A fiercely loyal fanbase and countless stories left untold in its dynamic universe.

10. Treasure Planet (2002)

This Disney animated film is a criminally underrated gem. A dazzling reimagining of Treasure Island in space, Treasure Planet boasts stunning visuals and a compelling father-son-esque relationship between Jim Hawkins and cyborg Long John Silver.

A sequel could continue Jim’s adventures as he fully embraces his destiny as a space captain. With space opera still hugely popular, Treasure Planet deserves the chance to shine again for a new generation.

Why it deserves a sequel: A breathtaking universe and a story that feels far from finished.
