Well, Snake, I tracked down the Patriots' Wisemen Committee, but all I found was a note. Snake:
What does it say? Otacon: "Buy the sequel! Coming soon!" Snake:
Damn you, Kojima
A Sequel Hook is something in a work that suggests that there is a clear possibility for another story. The MacGuffins
may come in threes, the Big Bad
might be Not Quite Dead
, or, more blatantly, as the story ends another adventure might be shown beginning.
The original work still has closure but, by leaving minor plot elements unresolved
, the writer has made writing a sequel easier. If the audience demand is there, they'll be ready. In fact, this method is so common the audience will identify any
unresolved plot element or any ending short of Happily Ever After
or Kill 'em All
as a hook. Sometimes the hook was just that, the writers are not sure which direction they would be going in the later movie.
Pretty much every film based on a comic book sets itself up for a sequel, and any movie that goes out of its way to establish a very expansive universe that has room for a sequel. In the case of adaptations their source is usually a medium known for making multiple storylines and, in most cases, have a decades-long Myth Arc
to mine for ideas.
If the Sequel Hook revolves about a character other than the main character, it may indicate a possibility of Changing of the Guard
Make note that a Sequel Hook is not a combination of a Mythology Gag
you noticed and wishful thinking. This is where the movie takes a brief side glance to let you know that more is coming. This is recognizable to almost anyone watching/reading, not just the fans that notice a minor gag in an adaptation.
If the story is complex enough, there can be a fine line between this and an outright Cliff Hanger
. And the two can overlap if the story concludes, everyone's happy and then a new problem shows up to put everyone in turmoil.
If a movie poses a Sequel Hook only for no sequel to ultimately be forthcoming
, this can be the source of unintentional humour later on down the track
Compare The End... Or Is It?
, Here We Go Again
, The Stinger
, And the Adventure Continues
, To Be Continued
, Saved for the Sequel
. Can occur as part of Inescapable Horror

Anime and Manga
- Back in 2008, the slighly random Kamen no Maid Guy actually set up a serious storyline - at the very end of the series.
- It had been made clear in Tokyo Mew Mew that Ichigo and friends had been de-powered because there was no need for them to fight. Then, we see everyone back at the cafe months later and, depending which version you're following, either their marks have reappeared and they transform, or Ichigo's cat ears reappear and Berii looks in the cafe window.
- A post-credits sequence in Strike Witches features Yoshika receiving a letter from her supposedly-dead father. But seriously, who saw the first two episodes and thought he was actually dead in the first place?
- The ending of Petite Princess Yucie has all the lead girls inexplicably attend the Princess Academy once more, even though they all graduated already. Yucie also seems to be no different as a Platinum Princess. But it's especially clear that a sequel was planned when all the girls shout "see you again" in the last shot. This was in 2003 and there still is no sequel in sight.
- Higurashi no Naku Koro ni, the end of the first season.
- Subverted in Fatal Fury: The Motion Picture, when Geese shows up halfway through the film to show us his RAGING STORM... and then is absent for the rest of the movie. Sequel time? Nope, they never made another.
- Bamboo Blade has Tamaki and a long-haired girl turn their heads to each other in the ending credits. Les Yay aside, this could mean that there is more in store.
- The six years later epilogue of Magical Girl Lyrical Nanoha A's, which has everyone talking about being reunited after a long time, the three Aces on their way to a mission, the brief introduction of Reinforce Zwei, and the scene cutting away just before said Aces reveal their new Barrier Jackets. All a hook for the A's to StrikerS manga to follow-up on around half a year later.
- Giant Robo has possibly one of the most sadistic, but not because of any fault of the writers'. The final OVA episode ends with the Earth decimated but able to recover, the IPO gutted of several of its top men, and Smug Snake Koumei informing the Magnificent Ten that all is according to the plan of Lord Big Fire, with Operation BR about to begin, suggesting that Big Fire is about to launch a true operation to conquer the world after Genya's plot both crippled their major opponent and simultaneously made sure the world would survive to be ruled over, leaving it ambiguous as to whether the entire operation was masterminded by Koumei or Big Fire himself. However, the sequel was unable to be made due to funding problems, so several critical explanations and Koumei's presumed come-uppance were never actually made, much to the frustration of the OVA series' many fans.
- Witchblade is practically BEGGING for a sequel. Due to its cliffhanger ending, canon incontinuities, and the fact the title artifacts parents (Angelus and Darkness) never got a role pretty much leave this show somewhat unresolved. If the comic writers give a shit about their canon (and the anime IS PART OF IT), they should bloody well rectify this.
- The last Slayers light novel ends with Lina and Gourry traveling to Lina's homeland, Zephilia. Cue loads of Will They or Won't They?. There's also the fate of Zelgadis and Amelia, considering that they were left to their own accord after the eighth novel (their replacements were Killed Off for Real in the last two novels), and Zelgadis' side story takes place after that time.
- The second anime season ends with Sylphiel running off with the heroes, but she's nowhere to be seen in the third (being replaced by Filia), so this is a subversion. Also, the last season has more of this than the third did, with Zelgadis riding on a boat contentedly sticking out among them.
- Blatantly lampshaded in Baccano!, when the two Meta Guys Carol and Gustav argue over why some plot threads are left untied (such as a scene in the first episode that never gets referred to again. At least in the anime...). Carol's answer? Sequel Hook.
- The second season of Hayate the Combat Butler ends with a new semester beginning for the cast, as well as a very brief shot of Athena during the final credits.
- For Heroman, Kogorr is defeated, and everyone is happy as the episode ends, fading to black. But, then it fades back in to show a prison island, with lights blazing and alarms shrieking. The prison's guards get decimated by Veronica, who frees Those Two Guys, and breaks down the wall to a certain cell, filled to the brim with equations and formulas, as well as drawings. A pencil is spit to the floor as the cell's inmate turns around: Dr. Minami. Cue To Be Continued. We even see a question mark afterwards.
- Pokémon Special would always use this at the end of an arc. It may seem a little silly, as the release of a new Pokémon generation already indicates a coming sequel, but it is often done to show either the new Big Bad, the direction they'll be heading with the next chapters, or just a way to explain how one arc leads to the next, chronologically.
- Red/Blue/Green - Averted. It makes sense for the first chapter, though, as there's no way they would've known that a new Generation of Pokémon would even exist (Yellow was out at the end of this arc, not Gold and Silver.) or if they would even continue with the series.
- Yellow - As part of the story, it's revealed that Yellow's journey had been engineered by Blue (The girl). While her reasons are not revealed, she's shown on her Poké Gear calling someone, discussing that she hadn't found what she needed through Yellow's adventure. The next we see is Silver, the rival of Pokémon Gold and Silver, hanging up, and a shot of Johto with a group of Generation II Pokémon as the chapter ends.
- Ruby and Sapphire - HUGE. After the battle, the Red Orb and Blue Orb used to maintain Groudon and Kyogre shatter into pieces. A shadowy figure shows up and picks up the pieces. Holding two red and blue shards, he says, reciting what comes across as a prophecy, "Creation of the new world order lies in thy hands." Next we see Giovanni, standing there with the shards, where his last words at the end of the chapter are "...And it has already begun."
- Especially shocking as this occurs after a Happily Ever After ending, where almost every loose end is tied up.
- FireRed and LeafGreen - Arguably larger than Ruby and Sapphire's. After the Big Bad is defeated and the characters all get their just endings, Sird shows up as Mewtwo flies away, using the last amount of energy she could attain for one last attack... Which turns the Pokédex holders to stone. And with that, the arc ends.
- Emerald - Crystal, looking back at the photographs from the battle, recalls Archie's last words when she confronted him about the origins of his suit of armor. She asks him who gave it to him, but he can only get out the beginning of the word before dying, as his last word is: "Galac..."
- Diamond and Pearl - So Cyrus has been defeated, Dialga and Palkia are peaceful again, and Platinum has finally achieved her goal of making the Berlitz family crest. Everything should be back to normal now, right? WRONG. She then states her intentions of rescuing her original bodyguards, then a weird scientist suddenly shows up, Byron and the researchers stop him, but they accidentally manage to open up a black hole, where a large claw swoops down and sucks in Dialga, Palkia, and Cyrus. The scientist just grins, tells Platinum his name and about the Distortion World, and escapes. Dia manages to take his notebook from him, which reveals information about the legendaries. Flash forward to Flint and Volkner having a conversation, where Flint reveals that he's in the Battle Zone. Another flash forward two weeks later, where Platinum's mother is on a cruise ship, and she and her daughter have a talk about the Distortion World.
- An episode of Pokémon that took place near the end of the Kanto arc ended with a shot of Mewtwo destroying the Team Rocket base and flying away, therefore setting the stage for Pokemon The First Movie.
- Panty & Stocking with Garterbelt ends with what is basically an Up to Eleven version of this trope, with sudden, completely nonsensical plot twists thrown out left and right just after everything has been resolved. Basically, Stocking pulling a Face-Heel Turn and slices Panty into 666 pieces, and Big Bad Corset pops out of Brief's penis (It Makes Sense in Context, I swear) to tell Brief that if he wants to save Panty, he must follow the pieces to the next town and unlock the hellgate there. Your typical Gainax Ending, as it were, but taken to eleven.
- Also, the whole thing may actually just be a parody of this trope; the creators have been very coy about a second season, and it's quite possible they have no intention of making one and came up with an asspull sequel hook just to troll the fans.
- It's also quite likely that, knowing them, they will make a second season but completely ignore the cliffhanger.
- Most likely a typical Gainax troll, but who's up for Brief and Chuck with Garterbelt?
- Gundam 00. Both seasons. Season one: Setsuna's line: "As long as the distortion continues to exist, I will continue to fight... Alongside my Gundam." Also, Tieria's "This is the Gundam that will change the world..." while we see a container saying "GN 00 00 GUNDAM". In season two, Tieria's "The true goal of the Aeolia Plan was to prepare Humanity for the dialogues to come." And after the Credits, we see a 15 second teaser for the movie, which ends with the text: "2314: The Childhood of Humankind Ends." If those don't practically say "There'll be another season" and "We're planning on making a movie", I don't know what does.
- The last episode of Puella Magi Madoka Magica, especially The Stinger. The director has stated that he wants to do a second season- though it's unknown whether he wants a genuine sequel or a Spin-Off.
- Fullmetal Alchemist averts this to the point where it seems like the writer was literally trying as hard as possible to prevent any possible sequel or need for a sequel. The 2003 anime version on the other hand ends with Ed getting ready to do another transmutation to get Al back by sacrificing himself. The Conquerers of Shamballa movie fittingly picks up a short time after the hook, with Ed stuck in the "real" world after his transmutation was successful.
- The creators of Death Note have themselves admitted that they are undecided whether The Death Note that Aizawa was holding at the warehouse was real, or if Light's bluff about it being fake was true. They claim that if the book was a fake, the real one is still out there somewhere, meaning "Ryuk could return somehow..."
- In Pretty Cure All Stars New Stage, when Ayumi returns to normal from being Cure Echo, the uniform's bow drops off, turning into a Cure Decor, the MacGuffin for Smile Pretty Cure!, but it is never picked up by either Ayumi nor the Smile team. Sadly, while Ayumi makes a cameo in New Stage 2, that's the extent of her appearance and thus we may not see her in action again.
- In the 13 and a half episode (no, seriously) of Tenchi Muyo!, after Mihoshi and Washu have their talk and we see what Washu's doing to Ryoko, we're cut to a scene where D3 is talking to Tokimi and we see a mysterious figure in the shadows. That figure, Z, would show up in the third season.
- As well, in episode six, we're introduced to Washu, who's Ryoko's "mother" and is incredibly smart, and Tsunami, who has a major connection to Juraians and Sasami in particular. Both of those are explored more in the first two episodes of the second season.
- Tiger & Bunny had the Ouroborus symbol appearing on a Stern dollar at the epilogue of episode 25. Also, Kotetsu and Barnaby coming out of their retirement and joining the Second League Heroes.
- In the final episode of High School Dx D, Sirzechs and Grayfia were discussing about how the Red Dragon Emperor (Issei) is now part of the devil society. It seems they were happy about Issei crashing the wedding until Grayfia mentions that the Vanishing Dragon will make his appearance. Cue the second season of the anime.
- Double Subverted at the end of part 1 of JoJo's Bizarre Adventure. Dio is defeated, Jonathan and Erina are married, they're boarding a ship to America for their honeymoon, everything points in the direction that the story is now ending. Oh, some guys are carrying a treasure chest onto the ship with a still-alive Dio in it, how cute. Hang on, we're seeing what happens right now? Hold the phone, did Dio just kill Jonathan?! Well, darn, that's a bit of a Downer Ending... wait, Erina is pregnant with Jonathan's child? The Joestar legacy lives on! Rejoice!
- Space Dandy's hell of a second season finale closes out with a card reading "May be continued?"
- A comic book example is found in the six issue Marvel Boy limited series from 2000. At the end, Marvel Boy ominously tells the government agents that in five months, the super prison he is in will become the capital for the new Kree Empire. After that, the caption advertises Marvel Boy 2:001!!!, a title that will likely not see the light of day, since Marvel Boy's next appearance was during the 2006 Summer Event Civil War.
- P.R.O.J.E.C.T.'s "Superman 2" vault at the end of All-Star Superman.
- At the end of Spider-Men, Peter makes it back to his own universe and starts wondering if his dimension has a Miles Morales (the new Ultimate Spidey). We don't see the results of his web search, but Peter is stunned.
- Most of The Ghost Map's final chapter is a Sequel Hook, with Sherlock Holmes, Dr. Watson, and Inspector Lestrade fully aware now that Moriarty is out there and will be returning. But it's the final scene with Moriarty himself that really clinches it.
- At the end of With Strings Attached, the four (especially Ringo) ask to be given another opportunity to use their magical bodies.
- My Little Avengers: After the "Where Are They Now?" Epilogue showing what's happened to all the characters in the year following Loki's defeat, the last scene shows Trixie essentially becoming the MLP version of Doctor Doom and swearing revenge on all who have opposed her.
- The last chapter of Mortality sets the stage for the next novel, The Road to Reichenbach, by showing Sherlock Holmes receiving an offer from the French government (as mentioned in "The Final Problem"). The epilogue goes on to sum up the characters with the Reichenbach Falls used as a motif.
- The coda of The Stars Will Aid Their Escape reveals that Nyarlathotep impregnated Fluttershy as a backup plan.
- Post Nuptials, the first story of The Nuptialverse, deals with the emotional fallout of Twilight's friends not believing her in "A Canterlot Wedding", and while most of it is dealt with, Spike still feels incredibly guilty and won't speak to Twilight. Meanwhile, Rainbow Dash senses something is wrong with Scootaloo, and Pinkie is dealing with her own family issues. All of these problems are dealt with in the sequel Families.
- The side story Metamorphosis ends with Chrysalis swearing revenge on Twilight, Shining Armor, and Cadance.
- Families ends with Discord contacting Chrysalis in a dream and ordering her to meet with an "associate" of his in order to plan his release. Meanwhile, relations with the dragons are now tense due to Garble's actions, and on top of that, several canon Season 3 events are alluded to (Trixie plotting her revenge, the reemergence of the Crystal Empire).
- At the end of Earth and Sky, Chrysalis is still on the loose, and has embarked on a scheme to replenish her strength by becoming a beloved foal actress.
- Hard Reset dangles one of these by way of a Cryptic Conversation.
- In the Total Drama story Courtney and the Violin of Despair, Courtney acquires the similarly cursed Violin of Doom at the end of the story. Subverted in that the story's closing note of uncertainty is actually a nod to the sci-fi classics of the 1950s, which tended to leave room for a sequel despite there being no plans for a sequel. So far as is known, the author has no plans to actually write a sequel (which would obviously be titled Courtney and the Violin of Doom); but he has stated that if he ever does, it might be something like The Perils of Pauline and would probably be openly pro-Courtney as opposed to the revenge fic subversion of the original.
- Faith and Doubt ends with the words "End of Volume 1" and credits. It then cuts to the five remaining elements of harmony discussing their plans to invade Equestria and take over the bodies of the Bearers.
- The sequel, The Abundance, does it again: Everything is wrapped up and the characters get a happy ending... except Princess Celestia and Luna's adopted father, Lord Tydal, escapes from the afterlife to warn them that the precursors to the ponies are coming and will be bringing hellfire with them.
- The Justice League of Equestria series has a setup of each story having two sequel hooks — one for each individual story's potential sequel, and the other being part of the setup for the eventual main crossover between all the storylines:
- Mare of Steel: First, there's the fact that Silversmith is still free, and has samples of Supermare's DNA to experiment on. Then, the last scene shows Darkseid opening a boomtube to Equestria.
- The Princess of Themyscria: Ares, defeated by Diana and now trapped in Tartarus, meets Circe, setting up a future Villain Team-Up. And then the last scene has Athena revealing to Hippolyta that Ares opening a portal to Tartarus has created a crack in reality that Apokolips can take advantage of.
- The New Look Series has a couple of these.
- Link's New Look 1 ends with Peach calls Toad to pick up some stuff that she plans to use on Link in the near future.
- Sonic's New Look 1.5 ends with Sonic leaving with his makeover undone, but Rouge has the security footage on the day's events and has plans for them.
- Examples from the Calvinverse:
- Shadows Awakening: The epilogue involves Captain Black recruiting the J-Team to head a new subdivision within Section 13 dedicated to magical threats, Tohru becomes a full chi wizard and takes on Jade as an apprentice, and in the last scene, Daolon Wong's apprentice emerging to take control of his resources, and the Big Bad mantle.
- MLP Next Generation: Know Fear! ends with three hooks: Starburst dedicates herself to continuing to fight the war, even as a renegade; meanwhile, unknown to her, Nox is raised as a Black Lantern; and in the final scene two more power rings — one orange, the other violet — arrive on Equestria. And a sequel has already been announced, and confirmed to, at least, address that last hook.
Films — Animated
Films — Live-Action
- "James Bond will return..."
- Back to the Future:
- Doc Brown whisks Marty and girlfriend Jennifer away at the end of the first film. The writers merely intended it as a closing gag, and later had to work out why he whisked him (and her) away. Word of God states that they would have not put Jennifer in the car if it was planned as a sequel hook, note that she never does little but pass out. That repeat of the end scene of part 1 at the beginning of part 2, while looking like a continuation picking right up at the Sequel Hook, was actually a re-filming of it with a minor Retcon, so that the new actors could match up with the footage to follow, and so that they could subtly insert a moment in which Doc has a new reaction to Marty asking whether he'll become an asshole in the future that is more appropriate to what Part 2 portrays. (In the original version of the first film's end scene—the one from the first film—he immediately brushes off the question with a sincere-sounding reassurance that "both you and Jennifer turn out just fine". In the re-filmed version of the scene at the beginning of part 2, he says the same line, but this time hesitates first with some hems and haws and an "oh shit, I wish he hadn't asked me that" look in his eyes.) A rare case of a Sequel Hook actually going against itself.
- The second movie uses the 1955 'end' of the first as a hook into the third film; as soon as Marty's gone back to the future and Doc Brown's celebrated his good work, the Marty from slightly later in the future appears and tells Doc that he's "back FROM the future!"
- Mortal Kombat concluded with victory and ended on a cliffhanger, as Shao Kahn, the Man Behind the Man of the movie's Big Bad, shows up and announces he's come to take their souls. Raiden's response: "I don't think so."
- Superman is a rare case of a film having a sequel hook at the beginning; General Zod, Ursa, and Non are banished to the Phantom Zone in the film's opening scenes, and are not seen again until they return as the Big Bad and Dragons in Superman II. That's because Superman 1 and 2 were originally filmed together. After the entire project fell behind schedule and over-budget, the studio called Richard Donner up and told him to finish up the first film and leave the sequel for later.
- The first X-Men film had the team watching a press conference near the end and noticing that Senator Kelly was being impersonated by Mystique. Logan is also riding off to track down hints given about his past.
- The Phoenix underneath Alkali Lake in X2: X-Men United.
- X-Men: The Last Stand, despite being the final chapter in a trilogy, has a potential sequel hook in its final seconds; the de-powered Magneto, homeless and alone, sits at a (steel) chessboard in Central Park vainly trying to make the pieces move; one pawn wobbles, almost imperceptibly, in the instant before the shot cuts to Brett Ratner's director credit. There is even a second hook after the credits, showing that Xavier survived in the Chekhov's Gun. (eww.)
- The Stinger at the end of X-Men Origins: Wolverine shows Logan drinking away his sorrows in a Japanese pub. Logan's next solo film, The Wolverine feature Wolverine's adventures in Japan. However, due to the poor reception of Origins, The Wolverine actually ignores the events of Origins, and instead takes place years after the events of The Last Stand.
- X-Men: First Class ends with Erik becoming Magneto for the first time and busting Emma Frost out of prison.
- The Wolverine ends with Wolverine and Yukio heading out to have new adventures across the globe, with Logan finally having accepted his role as a warrior and hero. The Stinger sets up a sequel hook for X-Men: First Class's sequel X-Men: Days of Future Past by showing Logan being confronted by a repowered Magneto and a Back From The Dead Xavier, wanting him to aid them in stopping the upcoming Sentinel threat.
- Two of them in X-Men: Days of Future Past. First, Mystique rescues Wolverine from the river Magneto threw him in, though we know that turns out alright. The Stinger gives us a glimpse of Apocalypse and his Four Horsemen.
- The Garbage Pail Kids Movie, of all things, had one with the titular kids escaping and hitting the road. Thankfully, it flopped at the box office and no sequel was made.
- The Godzilla (1998) ends with a shot of a single left-over Godzilla egg preparing to hatch. The film was intended as the first chapter of a trilogy; as it bombed, however, no sequels were made (at least, not in America). The hook did figure into the premise of the Animated Adaptation Godzilla: The Series, however.
- A very similar "single left-over egg hatching" sequel hook is the final shot of 1982's Q: The Winged Serpent. The film didn't do well enough to merit a sequel.
- Species ends with a rat eating the corpse of one of the aliens, and getting possessed from doing so. This was completely ignored for the actual sequel.
- The 1980 Flash Gordon movie had someone pick up Ming's ring after the story ended; since the movie was a bomb, nothing came of it. Possibly in homage, the third series of the revived Doctor Who ended with someone picking up the Master's ring and laughing evilly.
- National Treasure
- The original ending of the first film was thought to be a Sequel Hook by test audiences, so the filmmakers shot a new ending and put that one in the movie. (You can see the original ending on the DVD.) Ironically, the film made so much money that it got a sequel anyway.
- Ironically, played straight in the sequel, Book of Secrets. At the end of the film, the President asks Gates to look into the mysterious Page 47 of the titular book. Though the contents of the page are never mentioned, Gates describes the information contained within as "life altering".
- The Matrix franchise:
- The original The Matrix ends with Neo making a call to the machines and telling he's going to show the people within the Matrix the truth of the world, followed by a shot of him flying into the sky.
- With The Matrix Reloaded and The Matrix Revolutions being filmed at the same time, like Back to the Future, Reloaded contains one in the last shot: an unconscious Neo in the Hammer infirmary...and an unconscious Bane-slash-Smith on another bed.
- Biggles Adventures In Time finished with our American time-traveller getting zapped in to help Biggles escape from a cannibal cooking pot. It may even have finished "To Be Continued..." The film bombed and no sequel was made.
- The 1998 film version of Lost in Space does this as well: all is well and the villain has been spared and is still aboard, but suddenly a Negative Space Wedgie threatens the ship. The only option is to hit the button that randomly zaps the ship to another point in the galaxy (why do they even have that button?) to who-knows-what adventures. We don't know what adventures: the film bombed and - you guessed it...
- They did have the coordinates for Alpha Prime...
- "Manos" The Hands of Fate not only ends with "The End?", but also conspicuously allows Torgo to escape.
- Another Mystery Science Theater 3000 subject, Space Mutiny, ends with the main bad guy proving to be Not Quite Dead. Naturally, Mike and the Bots are Genre Savvy enough to see this one coming:
"Aaaand his Eyes Open
"His eyes open!"
"Hurry up and show it!"
- Blade: Trinity: The audience is led to believe that Blade died fighting Drake/Dracula, but just before the credits roll, Drake is still alive, and the audience sees Blade riding away on his motorcycle, set to fight again another day. This actually depends on which cut you're watching.
- XXX State Of The Union ends with Gibbs entering an elevator while discussing with his anxious attendants who he has in mind for the next candidate for the xXx position.
- From the Marvel Cinematic Universe:
- Iron Man has James Rhodes looking at the older Mark II silver-and-grey armor and says "Next time, baby", an obvious foreshadowing of his becoming War Machine (ironically this is not to be, at least for Rhodes' actor). The brief after-credits scene has Samuel L. Jackson as Nick Fury declaring the existence of other superheroes and the "Avenger Initiative" is about as blatant as a Sequel Hook can get without being a Cliff Hanger.
- Overlooked because of how awesome it was, but Tony telling a press conference outright that he was Iron Man not only subverts the Secret Identity thing but makes you wonder where they are going to take that.
- After Agent Coulson got called away in the middle of Iron Man 2, The Stinger shows that he was sent to a strange alien hammer that landed in the middle of the New Mexico desert. The talk with Nick Fury and the map in the background was meant to foreshadow other Marvel characters who were being primed for future film appearances. The most notable might be the indicator in Africa, meant as a nod to the Black Panther.
- The Incredible Hulk had Samuel Sterns head mutating, hinting at him turning into Leader. Tony "Iron Man" Stark makes a cameo announcing that they're putting a "team" together.]] In the end Bruce attempts a controlled transformation with an ambiguous smile on his face. According to the DVD commentary, whether the smile indicates that he'd actually gained control or not would depend on which came first: another Hulk movie (where Banner wouldn't be in control) or The Avengers (where he would).
- The unknown fate of Bucky Barnes in Captain America: The First Avenger, as well as the Red Skull's spectacular "death" work as sequel hooks for future Cap movies.
- Thor contains a post-credits sequence revealing that Nick Fury is in possession of the Tesseract, and that Loki is still alive and controlling Doctor Selvig. This directly leads into The Avengers and foreshadows the events of Captain America: The First Avenger.
- The Avengers itself ends with the Other lamenting the Chitauri invasion has failed as humans are "too unruly", and claims trying to take them on again would be "courting Death." Cue The Reveal of Thanos, smiling at the thought.
- Also it shows Tony making some modifications to the Stark Tower, to perhaps accommodate his fellow Avengers should they ever be needed to assemble once again.
- Guardians of the Galaxy has The Reveal that Star-Lord is only half-human and that his father sent Yondu to abduct him for unknown reasons, Drax shifts his vendetta from Ronan to Thanos, and Nebula is still alive.
- Batman Begins: "Take this guy: Armed robbery, double homicide. Has a, taste for the theatrical, like you. Leaves a calling card."
- This is a Shout-Out to Batman: Year One, which ends exactly the same way.
- The Dark Knight itself has a huge sequel hook, edging into cliffhanger territory: The series can't very well end on Batman being demonized and hunted, so how will he atone for Two-Face's crimes and regain Gotham's trust? Yet that ending is so organic and un-gimmicky it takes a minute to recognize it as a hook.
- Alien vs. Predator: The PredAlien chestburster at the end prompted an immediate reaction of "Well, they've set up the sequel nicely then..." and sure enough, said sequel opens on the same scene, even. Reshot, admittedly, but recognisably meant to be identical.
- The sequel ends with a Sequel Hook of its own. At the very end, Colonel Stevens puts the predator's gun in a box saying that "This isn't for our world, is it Ms.Yutani?" and it ends just like that. Unfortunately, due to the poor success of the first two, they probably won't make a third one.
- Played with in Indiana Jones and the Kingdom of the Crystal Skull: the last scene has Mutt about to pick Indy's Nice Hat (which a gust of wind blew off its rack and towards him) only for Indy to grab it right before he has a chance to put it on..
- Star Wars: A New Hope had Darth Vader's ship fleeing after the destruction of the Death Star. The Empire Strikes Back blurs the line between Sequel Hook and a Cliff Hanger, as the primary goal of escaping the Empire was concluded, but Vader's revelation and Han Solo being taken to Jabba the Hutt meant there was plenty of story for the sequel.
- Each film of the prequel trilogy had a Sequel Hook as well: The other Sith still hidden from the Jedi at the end of The Phantom Menace, the start of the Clone Wars at the end of Attack of the Clones, and Obi-Wan, Yoda, and Bail Organa making their plans for the future at the end of Revenge of the Sith (the last one, of course, leading up to the original trilogy).
- Particularly blatant (and incontinent) one in The Last Starfighter. The Dragon, having been deposed and arrested on orders from his Man Behind the Man overlord, kills his two guards with his flicknife sceptre (which he has already shown off to everybody) and escapes.
- They weren't quite as stupid as that makes it sound. They took it away from him, but he took advantage of his guards being (literally) off-balance due to Alex firing on the command ship and got it back.
- The dire and dismal Hawk the Slayer has this one on its list of crimes. Hawk's evil brother, Voltan, appears to Hawk and Co. to be acting alone, but the audience can see that he is just a subservient Dragon to the shadowy, hidden Big Bad. He gets killed, but the final scene sees his corpse being borne away from its burial chamber by said Big Bad for resurrection. Fortunately, it didn't happen.
- Harold & Kumar Go to White Castle ends with the title characters planning a trip to Amsterdam.
- Spoofed in Kung Pow! Enter the Fist (as most things were in that movie), both when Wo claims to meet the Chosen One again... "many times... in the sequel". There is also a clip of a "sequel" at the end of the movie, but this is comprised almost entirely of scenes that got left on the cutting room floor.
- The trope image is from Mac and Me, which ended with the eponymous alien and his family becoming U.S. citizens and driving off in a car with a sign on the back with a big pink bubble showing up at the end saying "We'll be back!". Thankfully, this was not followed through with due to the movie's box office failure. Mind you, this is the same movie that shamelessly ripped off E.T. and featured product placements up the wazoo.
- The Neverending Story:
Narrator: Bastian made many other wishes and had many other amazing adventures before he finally returned to the ordinary world. But that's another story.
- Of course, since the movie only used part of the book for its story, it was probably originally meant as a reference to that.
- Conan the Barbarian (1982) ended with a shot of Conan as the king. This was eventually followed up in Age of Conan's intro, which shows King Conan sparring with one of his spies and planning for war.
- The end of Red Dragon (movie only) could count as a prequel hook: A young, female FBI agent wants to talk to Dr. Lecter.
- Young Sherlock Holmes features a post-credit reveal that one of the characters in the film would eventually become Holmes' nemesis, Professor Moriarty. Shame that there was no sequel (beyond the books, of course), because the flick wasn't that bad.
- A title at the end of The Sword and the Sorcerer announces that its sequel would be called Tales of an Ancient Empire. It was never produced.
- Until 2010, that is. Not that the sequel has much to do with the original...
- A title at the end of The Adventures of Buckaroo Banzai Across the 8th Dimension announces that its sequel would be called Buckaroo Banzai vs. the World Crime League. It was never produced.
- Each Resident Evil film end with one.
- The first ends as Alice wakes up to find Raccoon City ravaged by a Zombie Apocalypse.
- Resident Evil: Apocalypse ends on the prospect of Dr. Isaacs having control over her similar to the Nemesis.
- Resident Evil: Extinction shows her waking up an army of clones and vowing revenge on Umbrella.
- Resident Evil: Afterlife has Jill, in her battlesuit, along with a squadrop of Umbrella VTOLs.
- Resident Evil: Retribution ends with Wesker injecting the T-Virus back into Alice, and Wesker tells Alice, Jill, Ada, and Leon that the Red Queen has declared an all-out war on humanity, and that this is the last stand.
- In the same canon of the original games, Resident Evil: Degeneration shows that WilPharma's assets have been acquired by TriCell. The ending for the ride Biohazard 4D Executer has Dr. Cameron escaping the city, having become a practically immortal creature capable of Grand Theft Me.
- District 9: Christopher promised he'd be back in three years- with reinforcements. We have it coming.
- G.I. Joe: The Rise of Cobra: Cobra Commander (actually using that moniker, to be exact) and the masked Destro appear only almost at the end, the US President whistling a certain tune and the Joes going off on another mission.
- G.I. Joe: Retaliation: Cobra Commander is still at large and there's a possibility that Destro, who was left in the Prison by Cobra Commander, may return as a threat in a possible sequel.
- The Live-Action Adaptation for Alvin and the Chipmunks ended with the movie's Big Bad, Corrupt Corporate Executive Ian Hawke, trying to get squirrels to sing. Like the Back to the Future example above, this is a Sequel Hook only in retrospect.
- The Street Fighter film and Masters of the Universe both have Not Quite Dead endings.
- City Slickers 2 ended with Duke handing Mitch a piece of gold from the Washburn treasure.
- Sherlock Holmes with all of its nods to Moriarty.
- The premise for the sequel is essentially set up in the last few minutes, because it's revealed that Moriarty stole the radio transmitter device and is willing to use his massive wealth to wreak havoc. Holmes agrees to go after Moriarty at the very end of the film.
- Eragon ends with Eragon and his dragon defeating the forces of evil. Then shortly before the credits roll, the film's Big Bad slices open a large tapestry to reveal his own Dragon, which would presumably do battle with Eragon in the sequel. Luckily, Eldest (the next book in the series) was never filmed.
- Slither ends with a post-credits scene of the alien Not Quite Dead and infecting a cat. Sadly, the film didn't do well enough at the box-office to get a sequel.
- Star Trek II: The Wrath of Khan was not expected to have a sequel, but Spock's "Remember..." mind-meld with McCoy was added just in case.
- Pirates of the Caribbean
- Pirates of the Caribbean: Dead Man's Chest: "So tell me.... what's become of my ship?"
- Then there's another example from Dead Man's Chest: the former Commodore entering Lord Beckett's office with the heart.
- Pirates of the Caribbean: At World's End has Jack stealing the map from Barbarossa that mentions the Fountain of Youth.
- Pirates of the Caribbean: On Stranger Tides ends with Angelica finding the voodoo doll of Jack that was thrown off the cliff earlier in the film.
- Plus Barbossa gaining Blackbeard's ship and magic sword and Jack regaining The Black Pearl, albeit stuck in a bottle, and heading off with Gibbs to find a way to restore it.
- At the end of Ip Man 2, we are introduced to young Bruce Lee, who Ip tells to come back when he's older.
- Anybody remember the Super Mario Bros.? Princess Daisy bursts into Mario and Luigi's apartment armed with a BFG, proclaiming "Guys... you're not going to believe this". Then everyone follows her out the door and the movie ends. There was no sequel, but nearly 20 years later, graphic novel sequels are planned.
- At the end of the John Hughes movie Baby's Day Out, baby Bink picks out a book entitled "Baby's Trip to China", but due to the movie's gratuitous Tastes Like Diabetes moments, as well as Hughes' untimely death, the sequel never came.
- "Machete... Will Return in... Machete Kills! And... Machete Kills Again!"!
- The Fast and the Furious franchise:
- Maverick. When Maverick only hides half of his winnings in his boot, allowing Annabelle to steal the other half, he admits that he did it intentionally because it will be fun to get it back.
- Dylan Dog: Dead of Night has a sequel hook where it is implied that Dylan and Marcus will have more adventures and fight new monsters (with a new monster appearing in the last shot). It is also revealed that Gabriel survived the vampires' attack against him. However, the film's poor reviews and box office will most likely prevent a sequel.
- The Other Guys ends with the Big Bad still at large and rather ominously telling us that "soon, Lendl will be everywhere!" (Lendl is the corporation she runs). It's difficult to say if this was an intentional sequel hook, but it certainly makes for a good jumping-off point for a sequel.
- Mystery Team ends with the trio meeting meeting a nameless man holding a photo of him having sex with a panda in a secret lab, and finally realizing that he had been castrated
- This may have been more of a Here We Go Again moment than anything, since just prior to that, the members of the Mystery Team were all preparing to go their separate ways and off to college.
- Merlin and the War of the Dragons ends with Merlin killing the evil wizard, Uther is proclaimed King of the Britons, general rejoicing and then Nimue resurrects the evil Wizard. The moie was made in 2008, I haven't heard of a sequel yet.
- Fu Manchu Hammer horror movies always end with him saying "The World shall hear from me again."
- Predators has the survivors watching a new bunch of people being brought into the deathworld to be hunted.
- The Three Musketeers (2011); Buckingham manages to rescue Milady de Winter from falling to her death, and announces that he's going back to France. Cut away to a shot of a fleet of British warships, with a fleet of air-ships overhead.
- Waxwork ends with the wax museum of the title burning down and Mark and Sarah escaping, but the still animate hand of a wax zombie also escapes. Although it's not really the main conflict of the story, Waxwork II: Lost in Time picks up immediately after that sequel hook, with the main characters trying to stop the hand from wreaking havoc.
- Splice: At the end of the film, Elsa is pregnant with Dren's baby, and the boss thanks Elsa for her readiness to carry on with "phase two" of the project
- Parodied in Men In Black II. After the big finale J notes that there's no way anyone didn't notice everything that just went down and no real way for the government to Hand Wave it away. The dialogue heavily implies that the events of the movie will cause the Men in Black to become public knowledge. Cue K using a large scale neuralyser hidden in the Statue of Liberty to erase the memories of the night of every single person in New York who isn't an MIB operative.
- Innerspace ends with Jack Putter jumping into and spinning off in a convertible with the intention of stopping the now-miniature Victor Scrimshaw and Dr. Margaret Canker from harming the newly-married Tuck and Lydia.
- Journey 2 The Mysterious Island ends with Anderson presenting Sean with Jules Verne's From the Earth to the Moon as a birthday present, saying it's an adventure he wants the whole family to take. The camera then pulls upwards, above the house, into the sky, into orbit and to just behind the moon.
- Jack the Giant Slayer: Near the end of the film, set in modern day London, a boy named Rodey grins evilly at the royal crown (actually the crown of King Erik) and carries with him a backpack similar to Roderick's. This heavily implies that he is a descendant of Roderick (or at least a descendant of any siblings or cousins Roderick may have had, as he never had any children himself) and plans to do what his ancestor did centuries ago.
- At the end of Master and Commander: The Far Side of the World, HMS Surprise finally catches up to the French ship Acheron after chasing it for 138 minutes. In the ensuing battle, the British win and capture their quarry. A prize crew is put on board to take it and the imprisoned French crew to a friendly port. As the captain of the Surprise relxes afterwards, his friend says something to make him think the French might attempt to recapture their ship, so the captain begins chasing it. Just as the audience thinks that the film might never end, it does, leaving the resolution of the chase for a sequel that, thus, far, has not yet been made..
- The Musketeer (a 2001 adaptation of The Three Musketeers) ends with D'Artagnan whispering the Hook into the ear of Cardinal Richelieu: "Bless me Father, for I will sin. One night, I will come for you."
- The Rocketeer ended with Jenny Blake giving Peevey back his reverse-engineered blueprints for a new and improved version of the rocketpack, which were stolen by Lothar earlier in the film.
- A LexCorp logo adorns several trucks and building sites in Man of Steel, hinting at Clark's future Earth-born nemesis.
- The end of Now You See Me desperately screams 'sequel'. Apparently it's getting one.
- Parodied in History of the World Part I, which contains sequel hook material promoting History of the World Part II, which was never intended to be produced. Viewers were given previews of concepts such as 'Hitler on Ice' and 'Jews in Space', simply as an excuse to shoehorn such silly material into the film.
- The Last Airbender: As with the show it's based on, it ends with a shot of Ozai assigning Azula the task of capturing the Avatar. But of course thanks to the dismal box-office returns, the planned sequels that cover the rest of the series were quickly scrapped.
- Deliberately averted in Godzilla (2014) by Edwards. He says that he typically rolls his eyes at films that go out of their way to introduce plot points near the end for the express purpose of having them resolved in future instalments. He prefers to have a film that can stand perfectly well on its own. That said, the film's ending leaves itself open for a sequel, as Godzilla returns to the ocean, with the expectation that he'll return when humanity next needs him.
Edwards: "I want a story that begins and ends, and you leave on a high. That’s all we cared about when we were making this; just this film. If this film is good, the others can come, but let’s just pay attention to this and not get side-tracked by other things."
- In The Wolfman (2010), Lawrence Talbot bites Inspector Aberline.
- In Running Scared (the 1986 comedy with Billy Crystal and Gregory Hines), two cop partners plan to retire from the force and open a bar in Key West after their current case. They crack the case, then decide not to retire. A sequel titled "Still Running" was planned and different scripts were written, but Crystal and Hines rejected them all as too weak.
- In Killer Crocodile, main characters find the nest of the title creature and destroy its eggs. After the climax, the film ends with a scene that shows that one of the eggs survived, and a little croc hatches out of it. Since the film was shot back-to-back with its sequel, continuation to this set-up was delivered.
- Dead in Tombstone: Of sorts. Guerrero kills his old gang, but the Devil sabotages him so he doesn't succeed until past midnight (therefore breaking the deal). Satan changes the deal so Guerrero is forced to act as his bounty hunter for the rest of eternity. The movie ends with Guerrero riding to the sunset to his next target.
- In Teenage Mutant Ninja Turtles (2014), the Shredder falls nearly sixty floors to street level and is captured by the police, but he's seen taking a bit of mutagen on a fingertip and hiding it in his fist.
- Green Lantern has Sinestro convince the Guardians to forge a yellow ring to combat Parallax, only to be dissuaded by Hal as being a bad idea, which he ends up agreeing and later commends Hal for succeeding in defeating him without it. In The Stinger the yellow ring is later shown sealed away in a hidden chamber, with Sinestro taking the ring for himself, initiating an Evil Costume Switch.
- Man of Steel has Clark considering what he will do and how he will help people now that the world knows he exists. The last scene is him talking about what the best job would be to keep aware of world situations, and he dons the famous glasses and joins the staff of the Daily Planet. In more of a tidbit, logos are seen around the movie for both Lex Corp and Wayne Enterprises, with Lex Luthor and Bruce Wayne showing up in the sequel Batman v Superman: Dawn of Justice.
- The end of Dracula Untold, jumps to the present day - Vlad's still alive, and so is the Elder Vampire, now in a more human form. As well, Mina Harker is alive in the present day, or a reincarnation of her.
- Like Catching Fire before it, The Hunger Games: Mockingjay Part 1 ends on a massive cliffhanger: Katniss re-visiting Hijacked!Peeta.
- Jurassic Park ended with one of these where Dr. Grant, being kept in Costa Rica by their government who was still investigating the Isla Nublar incident, is approached by an agent of the U.S. government about a path of destruction being carved through South America by a group of 'strange reptiles' that are swarming farms and devouring plants with lysine, the amino acid Hammond had all the dinosaurs bred to be dependent upon. Unfortunately this hook was ignored and the followup book was a sequel to the movie.
- Rendezvous with Rama: After a mysterious alien object passes through the solar system, the book ends with the portentous sentence, 'The Ramans do everything in threes'. (Whether or not a second Rama, let alone a third, is presented in the sequels at all is debatable.)
- After the Philosopher's/Sorcerer's Stone is destroyed at the end of the first Harry Potter book, Dumbledore says that there are still other ways Voldemort can return. Voldemort spends the rest of the series proving Dumbledore right.
- Harry Potter and the Half-Blood Prince ends with Harry deciding to leave Hogwarts to find and destroy the Horcruxes that will make Voldemort vulnerable, which tells the reader that the series' traditional formula will be thrown by the wayside for the final installment.
- Some fans really hope that the controversial epilogue is one of these, despite the author saying that it is not.
- It's practically an anti- sequel hook, since it seems to only exist to assure us that they all lived Happily Ever After.
- It could be a sequel hook in the sense that it introduces a new generation of characters. But it doesn't set up any kind of continuing plot.
- Believe it or not, J. R. R. Tolkien adjusted The Hobbit in a later edition to help it be the prequel of The Lord of the Rings. Which would make it a Retcon Sequel Hook. In the first edition, the Gollum was honest in the riddle game and showed Bilbo the way out of the caves in recompense when he realized he could not give him the ring.
- Each book in J.R. Ward's crack-like Black Dagger Brotherhood series features a Sequel Hook embedded as the B- or C-plot of the current book. You'll be fiending for the next book before you've even finished the one you're on.
- Thursday Next is full of these, but they're so tongue-in-cheek and playful, they don't even seem like marketing gimmicks. One happens at the end of First Among Sequels, when Thursday discovers that since someone has been trying to get rid of literary serials, there's a serial killer loose in the Book World!
- Terry Pratchett's Moist von Lipwig Discworld novels (all two of them) have thus far contained sequel hooks. In the first, Going Postal, the Patrician Lord Vetinari is seen making an offer to one Reacher Gilt to reform the Royal Mint as the Post Office had been in the book. This task was eventually undertaken by Lipwig in Making Money, and at the end of that one Vetinari muses how useful an asset Lipwig has proved to be and also how the City's tax system is in dire need of reform.
- One of the next Discworld books is indeed rumored to be called Raising Taxes.
- The epilogue-like last chapter of Ender’s Game is titled "Speaker for the Dead," and was written to set up the identically-named sequel to the book.
- The last chapter of the first book of The Hitchhikers Guide To The Galaxy is essentially an advertisement for the Restaurant at the End of the Universe. The place was encountered in the radio series immediately after the episodes adapted into the first book; the second book was indeed named The Restaurant at the End of the Universe but did not reach the Restaurant until the middle.
- It's been claimed that the last chapter was added on by the editors to wrap up the completed pages after Adams missed his deadline.
- The Death Note novel Another Note: The Los Angeles BB Murder Cases has a note by the narrator in the final chapter saying that, if he had more time, he would write about two other stories L told him. A pretty blatant set-up for more novels like it.
- During the course of James Swallow's Warhammer 40,000 novel Red Fury, Fabius Bile obtained some of the "sacred vitae" from the Blood Angels. During the Dénouement, Dante informs Rafen of this, and sends him after it.
- Dale Brown has various hooks in his book-endings. For example, Battle Born ended with the Dreamland staffers offering Rebecca Furness command of a new unit, while Air Battle Force ended on the then Russian president threatening another war with the Americans.
- Older Than Feudalism: In The Odyssey, the prophet Tiresias tells Odysseus that he must make another journey after returning home, but this was not followed up on by Homer. That journey only appears in the lost Telegony, the last epic of the Trojan Cycle.
- The hook involved with the Kang's Regiment books is rather unusual in that it's not only in the second of the existing books (that number itself implies a third volume, because Dragonlance multi-part novels almost always come in groups of 3) but in the ending of the War Of Souls trilogy. In Draconian Measures, the city Kang is trying to reach so he can found a Draconian civilization is named Teyr. The readers know from material set chronologically later that Teyr is a Draconian city, and there's an interesting bit in Dragons of the Vanished Moon where a bunch of Draconians from Teyr show up and fight against Takhisis and her forces (keep in mind, Kang starts out as a faithful servant of Takhisis, so this is a Heel-Face Turn for him). Two unnamed but familiar Draconians appear among the collection of enemies Takhisis magics to her to watch the moment of her triumph, as well.
- On the last page of Foundation and Earth, Isaac Asimov sets up a sequel (in a way that is somewhat difficult to summarize briefly or without massive spoilers). Unfortunately, he didn't actually have any definite ideas for that sequel and he died before he could come up with one.
- Quite prevalent in The Dresden Files:
- Changes had Harry getting shot and dying as the last scene in the book.
- Ghost Story has Harry set to head to the Sidhe Court as the Winter Knight to do as Mab bids, leaving his friends not knowing that he did not die.
- Percy Jackson and the Olympians has a not so prominent one at the end of the last book, when the new resident Oracle spouts another prophecy. Though it is almost immediately Hand Waved with a "who knows when it could happen or if it's even about you guys" speech, it's pretty obvious that it will lead to a sequel series, which it has.
- The last sentence of Year Zero pretty much spells this out.
- The explicitly referenced buildup of magic at the other end of the Grand Bow River in Patricia C. Wrede's Frontier Magic.
- Daemon ends with Sebeck and companion setting off on a road trip across America, leading into their part of Freedom.
- Parellity ends with the main plot hook resolved, but some hanging threads, including Atlantis, what plans Abend has for Harborage and the gang, and everything to do with the Vaccine. Not to mention whatever the fuck was going on in chapter one.
- The end of the comic neo-noir City of Devils has Nick's next case coming through the door: the witch Hexene Candlemas, hiring him to find her toad.
- At the end of The Ultra Violets book 2, Power to the Purple, it's revealed that Opal and her mother have samples of the Iris's, Scarlet's, and Cheri's hair at BeauTek. Given the company's reputation for reckless genetic engineering, this is very worrying, to say the least.
- In the Rainbow Magic series, the Weather Fairies series ended with the girls receiving the fairy lockets, which promised many adventures ahead.
- Murderess ends with the introduction of a character named Tyler Killer, who is apparently very evil and probably not too bright, but extremely dangerous nonetheless.
- The first book of the Ahriman Trilogy has one of the more obvious ones: "And she was going to summon a god."
- A television show can do this with its story arcs; alerting you that just because the episode ends, the plotline will continue. Take the Star Trek: The Next Generation episode "Q Who". The Enterprise has narrowly escaped The Borg by the skin of their teeth. As Captain Picard and Guinan discuss their near-defeat, Guinan points out that humanity was never supposed to encounter them (the Borg) that early. But since they have....
Guinan: Of course, now...they know of your existence.
Picard (with understanding dawning): They're...coming...
- After Hiro Nakamura defeats Adam Monroe, he's shown trapped in a coffin, still alive; a clear indication that the character would return to menace the Heroes at some point later.
- Also, Sylar's body disappearing at the end of Season 1. Heroes loved this trope.
- Stargate SG-1 specifically left the door open on the Ori threat in its final episode, for the express purpose of setting up the follow up movie The Ark of Truth.
- Word of God is that they were, for the first time ever, not expecting to be cancelled, so they didn't wrap up the current plotlines. Oops.
- Doctor Who loves doing this in the new series with its season enders. Doomsday set up for The Runaway Bride. Last of the Timelords set up for Voyage of the Damned (and indirectly, for Time Crash). The End of Time set up for The Eleventh Hour (though in a sense any regeneration episode except Time and the Rani is a de facto Sequel Hook), and Steven Moffat has already said that The Big Bang sets up for the entirety of the next season (though the final lines, with the Egyptian Goddess on the Orient Express IN SPACE! is apparently a Noodle Incident). Oh, and Silence in the Library/Forest of the Dead? Set up for the run of River Song episodes this season.
- After the Master's dead body is consigned to the flames in an attempt to prevent him from ever regenerating, Doctor and Martha go. Then we see a woman's hand pull the Master's ring out of the ashes.
- The finale of series 6, The Wedding of River Song blows them all away with the reveal of the First Question. The Oldest Question in the Universe. The Question That Must Never Be Answered. That question is: Doctor Who?]]
- The oldest Doctor Who stories ended like this. The first story "An Unearthly Child" has the TARDIS land on another planet and the radiation meter rise without the TARDIS crew seeing.
- At the end of the Red Dwarf episode Polymorph, after the crew defeats the eponymous creature, it is revealed that a second one has made it on board. Subverted in the remastered version, in which on-screen text reveals that this one, much less intelligent than the first, took up residence harmlessly in Lister's underwear drawer and eventually died of old age. Doubly subverted by the episode Emohawk: Polymorph II three series later in which they meet another one.
- Arrested Development ends with Maeby meeting with director Ron Howard and pitching the story of her family as a TV show. In an obvious bit of foreshadowing, the final line of dialogue has Howard saying the story might work better as a movie. Sure enough, the series has been Un-Cancelled for at least one season by Netflix.
- The new season itself ends with a number of hooks for more episodes, such as George Michael apparently having impregnated a woman in Spain, Buster being accused of murdering Lucille 2, the web vigilante group Anonymous coming after the family, and Lindsay getting into politics.
- Merlin: Arthur's gone, but there *is* that legend of how he'll return when Britain needs him most. Plus, Merlin's still alive in the present day...
- The eleventh episode of Once Upon a Time seems like the series finale - until a Sequel Hook is brought by - who else - Captain Hook. A Sequel HOOK.
- This was also included in the season 2 finale, and in the season 3 finale as well.
- Agents Of SHIELD: Season 1 ends with quite a few dangling threads for Season 2 to pick up on: Coulson is now Director of S.H.I.E.L.D. and tasked with rebuilding the organization after the HYDRA infiltration; meanwhile, he has started to compulsively draw the same alien symbols that Garrett did after taking the GH325 serum. Fitz, meanwhile, is left in critical condition after his near-Heroic Sacrifice, with his future uncertain. At the same time, both Quinn and Raina escape Garrett's downfall, the former still in possession of the gravitonium, and the latter getting in touch with a mysterious figure who is apparently Skye's father.
- The season finale also had a nice subversion, where Garret starts to augment himself with cybernetic implants after everyone assumed he was dead. Right as it seems like he's going to be an even bigger threat for the second season, Coulson pops out of nowhere and casually vaporizes him mid-villain speech.
- Henry IV, Part 1 ends with news that Northumberland and Archbishop Scroop are arming for war.
- You'd think the "Part 1" in the title would kind of give away that a sequel was intended as well...
- Henry VI Part 3 ends with Richard of Gloucester's (the future King Richard III) monologue where he talks about how he'll do anything to gain control of the crown- setting up for "Richard III".
- Twelfth Night end with Malvolio pledging "I’ll be reveng’d on the whole pack of you!" which looks like a good setup for a tragedy to follow this comedy. Sadly, Shakespeare never did anything with it.
- It has been argued that the sequel this set up was the real-life closing of the English theaters by the Malvolio-like Puritans.
- KateModern special "Precious Blood" ends with "Precious Blood: 10:30PM", which shows that Terrence is still alive and has killed the Watcher.
- At the end of "The Last Work", Julia swears revenge on the K-Team, and some of them say they still want to fight.
- The lonelygirl15 Grand Finale "The Ascension" is followed by a short surprise video revealing that Lucy is still at large.
- Subverted in the Homestar Runner cartoon, DNA Evidence. In the end, it turns out that Strong Sad had the DNA Evidence all along, and then laughs maniacally... and then it turns out that Homsar was there, watching him. Somebody unfamiliar with Homestar Runner would guess he'd tell everybody the news, right?
- At the end of The Cartoon Man, both Roy and Karen are cartoonified, while Simon and Valerie get sucked into the Second Dimension. Both plot points play a major role in the follow-up, which itself ends on a major Cliff Hanger.
- Dusk's Dawn: We never see what happened to the antagonist, or when the protagonists went to Celestia. However, a new production hasn't been made in years, so it's either been abandoned or stuck in Development Hell.
- In Jackie Chan Adventures, after Jade destroys Shendu with one of his own Talismans, Uncle reveals that when an evil is destroyed, a new evil can fill the void, possibly being even more dangerous. The next season deals with Shendu's siblings forcing his spirit (which survived his body's destruction, likely due to the Sheep Talisman or demons naturally become spirits once they die), to take advantage to this void (via an ancient artifact), by using it to release them from their otherworldy prison so they can reconquer the world.
- Subverted in Superman: Brainiac Attacks; after Superman finishes pummeling Brainiac's body into scrap, the chip that remains of the original Brainiac is seen ominously blinking amidst the wreckage... until Superman's fist comes down on it, smashing it to pieces.
- Played straight in Superman: Doomsday, though: Lex Luthor, having been seemingly killed by the Superman clone earlier in the movie, turns up in a body cast at the end, musing over whether or not Superman is really impossible to destroy.
- The Family Guy Chicken Fights all end with the battered, mutilated, frequently shredded chicken opening one of its heavily blackened eyes. Even after it's been sucked through a jet engine, or pounded into submission with a saucepan, or...
- Zuko's question to Ozai at the end of the Avatar: The Last Airbender Grand Finale: "Where is my mother?"
- It did technically lead to Sequel Series The Legend of Korra... but it takes place over 70 years in the future and most of the former cast is dead. The first episode even trolls the audience about the hook, with a character asking about it and the explanation being cut off.
- There's also The Promise, a graphic novel Interquel trilogy set one year after the end of the War; in first installment, we discover the end of the conversation started by the above hook - which answers absolutely nothing. It even ends with the exact same sequel hook, only Zuko is now asking Azula about Mom instead of Ozai. Thankfully, the next comic interquel, The Search, has this plot hook as its central premise, so we'll finally get some closure.
- And then The Search saddles us with some more: Azula has escaped, and it's unclear whether she'll be redeemed. Also, Zuko and Mai are still broken up, despite Korra showing us that he had kids.
- Subverted in Danny Phantom with the episode "The Ultimate Enemy", where the Big Bad is shown to be contained, but not entirely defeated, as he was trying to bust out... But he never showed up again. (This was the result of Executive Meddling, canceling the show before they could go through with their plans to bring him back.)
- Justice League set up its second season as possibly the last, so they ended it in a truly epic finale with the watchtower base being destroyed. At the end and after Hawkgirl resigns from the League, Superman asks what they are going to do now, which Batman replies with "We rebuild." This leads into Justice League Unlimited, but was enough to be considered And the Adventure Continues.
- Batman: The Animated Series did this all the time, particularly in any episode introducing a new villain. There would always be a line at the end in which Batman suspects he hasn't seen the last of the new foe. Perhaps most blatant is the ending to the Ra's Al Ghul two-parter, in which Ra's falls into the Lazarus Pit and is presumed dead, but the final shot shows a hand rising up out of the pit while maniacal laughter is heard.
- At the end of Teen Titans season four, Big Bad Trigon has been defeated and the apocalypse averted, but Robin makes a point of reminding Raven that Slade, who'd been acting as The Dragon, is still alive and on the loose. This is never really followed up on, however as Slade only gets a cameo in the next and final season (though Word of God is that he was supposed to successfully become The Starscream to the new Big Bad, but it was scrapped for time constraints).
- Freddie as FRO7 had a huge one at the end with Freddie's evil aunt escaping and him getting called over to Washington D.C. There was in fact, already a sequel in the works, but it got shelved when the movie didn't do well and the American release cut half the hook out.
- In the U.S. Acres episode "Orson Goes on Vacation", Orson says he'll be on vacation for a week soon, and he asks Wade to be in charge again, but he refuses, a possible nod to "Temp Trouble", even though he was actually gone for two weeks in that episode, possibly because in a scene we weren't shown, he called them in the middle of his vacation to tell that he was going to have an extra week off. The person "in charge" in that episode is Aloysius Pig.
- It's not possible both episodes exist at the same time or connected since there was too many different scenes and mixing an old episode to a newer one doesn't fit Roy and Wade's Character Development of their friendship.
- Or maybe it took place in the future. This isn't the only time it's happened-the episode where they imagine it's summer during the winter took place a year after the episode had aired, because Wade says his family did something brave every 10 years, and the next time he would do this was in 2004. Said episode aired in 1993.
- Speaking of Aloysius Pig, in "Kiddie Korner", we have this little gem:
Orson Pig (singing): We'll bring to you, when we're back next time...
Aloysius Pig (spoken, as he's being hit with pies): HELP! HEEELP!
Orson Pig (singing): Something more wholesome than a nursery rhyme! note
- My Little Pony: Friendship Is Magic. The story normally takes place in such a way that any episode can happen any day, but Season 3's premiere ended like this, with Princess Celestia nodding at Princess Luna, who magically summons a book with stars and swirls on the cover.
- The season 3 finale (which incidentally pays off said Starswirl sequel hook) definitely is trying to draw you in for season 4. Twilight turns into an alicorn and is now a princess of Equestria. According to the writer's twitter, she considers this episode the first in a 3-parter.
- Considering season 5 was announced, plenty in "Twilight's Kingdom, Part 2". Such as the whereabouts of Scorpan in all of this, what new powers the rainbow elements entail and how Ponyville will now function as a kingdom, not to mention how Discord's completed reform will be displayed.
- BIONICLE: The Legend Reborn ends with Mata Nui and the other heroes discovering that uniting the settlements of Bara Magna (literally, by pulling them together) creates a Humongous Mecha and that the patterns on a stray coin and on the shield of a defeated Skrall soldier depict a map. They set out to find where it leads, with Mata Nui's friends determined to accompany him... and the toy-line got canceled, the sequel scrapped, so the story had to be wrapped up in a comic in which Mata Nui left his friends behind due to the page-limit.
- Randy Cunningham: 9th Grade Ninja: The end of "Randy Cunningham: 13th Century Ninja" suggests Catfish Booray will become a regular antagonist in later episodes.
- Taz-Mania: In one episode, Molly brings a kitty home and the kitty torments Taz behind Molly's back. In the end, the kitty held a sign saying "I'll be back". A later episode did feature the cat returning.
- Every season of Total Drama ends this way, with the exception of World Tour, Revenge of the Island, and Pahkitew Island.
- Gravity Falls: Stan's mantra of "Gravity Falls will return" is heard during the credits of "Gideon Rises".
- Wander over Yonder: The animatic during the end credits of "The Rider", shows the final shot from the end of the episode from a few seconds earlier, which pulls out to show Lord Dominator laughing maniacally, this may suggest that he may replace Lord Hater as Big Bad, or that they'll get involved in a Evil vs. Evil Big Bad Ensemble in Season 2.
