Hollywood loves a sequel. They love them so much they'll slap a number on anything that made more than twelve quid at the box office. But what about the films that are sequels but never told you? The ones that share characters, universes, or direct plot continuations with earlier films, yet marketed themselves as standalone stories? These sneaky bastards are everywhere, and once you know, you can't un-know.

Split (2016) - The Secret Unbreakable Sequel

This is probably the most famous example, but it still deserves pole position because of how brilliantly M. Night Shyamalan pulled it off. For the entire runtime of Split, you're watching what appears to be a self-contained psychological thriller about James McAvoy's Kevin Wendell Crumb and his 23 distinct personalities. It's tense, it's disturbing, McAvoy is doing about fourteen different Oscar-worthy performances simultaneously, and then - in the final thirty seconds - Bruce Willis appears in a diner as David Dunn from Unbreakable (2000).

The cinema reaction to that reveal was genuinely electric. People who hadn't thought about Unbreakable in sixteen years suddenly lost their minds. Shyamalan had secretly made a supervillain origin story set in the same universe, and nobody saw it coming. The fact that he kept it hidden through the entire marketing campaign is almost more impressive than the film itself. Almost.

Of course, then he made Glass (2019), which took all that goodwill and flushed it down the toilet, but we don't talk about that.

Sicario: Day of the Soldado (2018) - Wait, This Is a Sequel?

Right, technically this one has a subtitle that vaguely implies connection, but the marketing went out of its way to make it look like a standalone narco thriller. The original Sicario (2015) was a Denis Villeneuve masterpiece about the moral horror of the drug war. The sequel ditched Villeneuve, ditched Emily Blunt, and essentially became a Benicio del Toro and Josh Brolin action film that happened to share some character names.

Many people walked into Day of the Soldado having no idea it was a continuation. The tonal shift was so dramatic it barely felt like the same franchise. It's like ordering a perfectly aged steak and being served a microwave burger - technically both beef, functionally unrecognisable.

Bambi II (2006) - Disney's Stealth Midquel

Not exactly a hidden connection, but Disney pulled something genuinely weird here. Bambi II isn't a sequel at all - it's set between scenes of the original 1942 film. It takes place during the gap between Bambi's mother being murdered (still too soon) and Bambi growing up. They just... filled in the middle bit sixty-four years later. Nobody asked for this. Nobody needed backstory for a deer's adolescence. Yet here we are.

Hobbs & Shaw (2019) - Fast & Furious Without Saying Fast & Furious

Universal performed an interesting magic trick with this one. Hobbs & Shaw is absolutely, unambiguously a Fast & Furious spinoff sequel starring characters from the franchise. But the marketing leaned so heavily into "Dwayne Johnson and Jason Statham buddy action comedy" that millions of cinemagoers had no idea they were watching Fast & Furious 9.5. Some people genuinely went in cold and were confused about why everyone kept referencing events from previous films they'd never seen.

To be fair, the Fast franchise timeline is so incomprehensible at this point that even people who've seen every film are confused. Han died, then he didn't, then he did again, then he came back because apparently death is just a suggestion in that universe.

The Many Saints of Newark (2021) - The Sopranos Prequel Film Nobody Treated Like One

This film was marketed as a standalone mob drama that happened to be set in Newark. What it actually was: a direct prequel to The Sopranos featuring a young Tony Soprano played by Michael Gandolfini, the actual son of the late James Gandolfini. That's not a hidden connection - that's a direct bloodline sequel.

Yet the film went out of its way to feel self-contained, burying the Sopranos connections beneath a broader story about the 1967 Newark riots and Dickie Moltisanti's criminal career. If you hadn't watched the show, you'd have no idea this was essentially The Sopranos: Episode Zero. And honestly, even if you had watched the show, you'd leave the cinema wondering what the point was.

Prometheus (2012) - The Alien Prequel That Refused to Admit It

Ridley Scott spent the entire press tour for Prometheus insisting it wasn't an Alien prequel. "It shares DNA," he said, which is the most Ridley Scott non-answer imaginable. The film features the Space Jockeys from Alien, takes place on the same planet, involves Weyland-Yutani, and ends with a creature that's basically a proto-xenomorph.

But sure, Ridley. It's not a prequel. It just happens to directly set up the events of your 1979 masterpiece by complete coincidence. The refusal to commit to being a sequel was almost more frustrating than the film's confused mythology. Just own it, mate. We can see the facehugger from here.

10 Cloverfield Lane (2016) - The Cloverfield Connection Nobody Wanted

Here's a fascinating case study in franchise branding gone sideways. 10 Cloverfield Lane started life as a completely unrelated script called The Cellar. It was a tight, claustrophobic thriller about a woman trapped in a bunker with John Goodman at his most menacingly charming. Then J.J. Abrams's Bad Robot acquired it and bolted "Cloverfield" onto the title.

The connection to the original Cloverfield (2008) is tenuous at best - a shared universe where alien stuff happens, basically. But slapping that name on it turned a brilliant standalone thriller into a "sequel" that confused audiences expecting monster movie connections. The film is superb on its own terms. The franchise branding actively made it worse. Classic Abrams.

Joker (2019) - A Secret Taxi Driver/King of Comedy Sequel?

This one's more spiritual than literal, but hear me out. Todd Phillips openly acknowledged that Joker was heavily influenced by Martin Scorsese's Taxi Driver (1976) and The King of Comedy (1982). But "influenced by" undersells it dramatically. Arthur Fleck is essentially Travis Bickle meets Rupert Pupkin - a lonely, delusional man oscillating between violent fantasies and desperate bids for fame.

Robert De Niro's casting as Murray Franklin wasn't just a nod; it was a direct inversion. The man who played the obsessive fan in The King of Comedy now plays the talk show host being stalked. It's not a sequel in any legal sense, but it's a thematic continuation that's so blatant it might as well come with a bibliography. Phillips basically made a Scorsese cover album and won an Oscar for it.

Blade Runner 2049 (2017) - The Sequel People Forgot Was a Sequel

This isn't technically a "secret" sequel - it's right there in the title. But here's the thing: by 2017, so many people hadn't seen the original Blade Runner (1982) that 2049 functioned as a standalone film for a massive chunk of its audience. Denis Villeneuve crafted it carefully enough that you could follow the story without knowing about Deckard, the replicant question, or any of the original's mythology.

The result was a sequel that many viewers didn't realise was a sequel, which is either a testament to brilliant filmmaking or a damning indictment of cultural memory. Probably both. It's also a film that absolutely deserved to make ten times what it earned, but that's a rant for another day.

U.S. Marshals (1998) - The Fugitive 2.0

Remember The Fugitive (1993)? Harrison Ford running, Tommy Lee Jones chasing, everyone having a brilliant time? Well, U.S. Marshals is its direct sequel, following Tommy Lee Jones's Samuel Gerard as he chases a different fugitive played by Wesley Snipes. But Warner Bros. made the baffling decision not to call it The Fugitive 2, presumably because Harrison Ford wasn't in it.

So instead, audiences got a film that was clearly a sequel - same character, same role, same marshals - but branded as a standalone thriller. It confused everyone. Was it a sequel? A spinoff? A reboot? Nobody knew, and the box office reflected that confusion. Sometimes the simplest answer is just putting a "2" on the poster.

Why Studios Do This

The motivation behind stealth sequels is usually one of three things: creative ego (the director doesn't want the baggage of a franchise), marketing strategy (the studio thinks the original's audience is too niche), or legal complications (the rights situation is a nightmare). Sometimes it's all three simultaneously.

There's also the Tarantino approach - where every film exists in the same interconnected universe (Vic Vega and Vincent Vega are brothers, the Red Apple cigarettes pop up everywhere) but none of them function as sequels. It's worldbuilding without sequel obligations, and it's probably the smartest version of this trick.

The problem is when the hidden connection feels cynical rather than clever. When a studio buys an unrelated script and grafts a franchise name onto it - hello again, Cloverfield - audiences feel cheated rather than delighted. The magic of Split's reveal worked because it was planned from the beginning. The Cloverfield connections felt stapled on because they were.

The Bottom Line

Secret sequels are cinema's version of an Easter egg, and when they work, they're genuinely thrilling. That moment of recognition - "Wait, this is connected to that?" - is a uniquely cinematic pleasure. But they require trust. The filmmaker has to earn the reveal, and the audience has to feel rewarded rather than manipulated.

Otherwise, you're just slapping a recognisable name on an unrelated script and hoping nobody notices. And mate, we always notice.
