"Blackbeard came from the book, and in the book, there is a daughter character, too. But Jack Sparrow is not in the book, nor is Barbossa. So I wouldn't call this an adaptation."
— Terry Rossio, one of four writers of Pirates of the Caribbean: On Stranger Tides
- Open Water:
- Adrift, despite maintaining its original title in Europe and Australia, was retitled Open Water 2: Adrift in the United States despite the only thing it has in common with Open Water is that both feature people stuck in the middle of the ocean and the focus of the first film being sharks, of which there are none in the "sequel". The trailers of Adrift tease this by throwing in a "something touched my leg" line, which was just a false alarm in-film.
- Lionsgate did it again in 2017 with Cage Dive: While it retained its original title in some foreign markets, in the US it was rebranded as Open Water 3: Cage Dive. Again the only connection with the first film was people being stuck in the ocean, though this one at least has sharks in it unlike Adrift.
- The commentary track for Aliens reveals this trope was in play. When asked to do a sequel to Alien, James Cameron wrote an outline of his thoughts for a film, which was actually based on something he wrote a few months earlier with the Alien characters dropped in (it helped that it fit with what the producers had already thought about putting in a sequel).
- American Psycho 2: All American Girl: The film began production as an unrelated thriller, and was nearly finished filming when Executive Meddling decided it would be a sequel to American Psycho, and scenes tying it to the first film were hastily shot. According to Bret Easton Ellis, the idea came about after the studio intended to adapt The Rules of Attraction as a Serial Killer movie, but the filmmakers rejected the idea.
- The Bad Lieutenant: Port of Call New Orleans really has no connection to Bad Lieutenant other than featuring somewhat similar protagonists. Werner Herzog originally devised a film about a Dirty Cop set in New Orleans, but his production partners wanted to somehow tie it to the older film about a Dirty Cop (which like all of Abel Ferrara's works, is set in The Big Rotten Apple), for which they had purchased the rights and were angling for a franchise. While both are pretty gritty crime films with borderline-Villain Protagonists, Werzog's version is considerably Denser and Wackier, veering into Black Comedy at times.
- While Caligula was going through its Troubled Production, producer Franco Rossellini decided not to let millions of dollars in props come to waste and reused the scenery, clothing and even some of the cast in the comedy Messalina, Messalina. Given all this, and the fact it follows the next Roman emperor, it has been released as Caligula II. (The Cinema Snob's review noted it as a weird case of an official foreign knockoff, and one released before the main movie, no less!)
- Cloverfield:
- 10 Cloverfield Lane originated as a script called The Cellar. After Bad Robot optioned the script, it was re-tooled into a "spiritual successor" to Cloverfield. The film's eventual name was unknown even to its stars
until well into post-production. The big change is that, in the original script, Michelle escapes and drives towards Chicago, and finds a nuclear attack has taken place, rather than an alien invasion. - The Cloverfield Paradox is also an example, but unlike Lane, this movie was written and shot as a standalone film called The God Particle. The decision to Retool the movie into a Cloverfield sequel was made well into production, and rewrites and reshoots had to take place. Originally, the experiment was to search for the Higgs boson, which did NOT want to be found, only one mention of it remains in the final cut.
- 10 Cloverfield Lane originated as a script called The Cellar. After Bad Robot optioned the script, it was re-tooled into a "spiritual successor" to Cloverfield. The film's eventual name was unknown even to its stars
- Die Hard is in a unique position in that all of its sequels are based on source material completely unrelated to the novel that Die Hard was based on. (Meanwhile, Die Hard itself is a Divorced Installment.)
- Die Hard 2 was an adaptation of a novel by Walter Wager called 58 Minutes, which focused on an off-duty cop who has to stop a group of terrorists at an airport. The plot and characters were reworked to include the McClane character, while adding more action sequences.
- Die Hard with a Vengeance was based on an original screenplay titled Simon Says. It was also considered for use as the third Lethal Weapon sequel, which became another film entirely.
- Live Free or Die Hard (also known as Die Hard 4.0) was based on a combination of a magazine article titled "A Farewell to Arms" and an original screenplay titled WW3.com.
- A Good Day to Die Hard is about the closest there's been to a Die Hard film actually beginning life as a Die Hard film. But even so, the screenplay was a rejected one for the 4th film.
- Speed 2: Cruise Control was first written as a Die Hard 3, which certainly explains why the film has a "Die Hard" on an X setting dissonant from the original Speed.
- At least two of the Dirty Harry sequels started life as unrelated scripts. The Enforcer was a script called Moving Target, based on the Symbionese Liberation Army, which became a Dirty Harry story after Eastwood read and liked it. Similarly, Sudden Impact was intended as a standalone vehicle for Sondra Locke, before being reworked into a sequel.
- Ebirah, Horror of the Deep AKA Godzilla Vs The Sea Monster was originally going to feature King Kong instead of Godzilla. This becomes quite evident when Godzilla starts acting like King Kong. He is revived by electricity (like King Kong in King Kong vs. Godzilla, and very unlike the Godzilla of that movie). Yes, he even shows interest in a female human.
- Halloween III: Season of the Witch is sometimes thought to be an example of this, since - unlike the other Halloween films, it does not feature the Michael Myers characternote . However, it was always intended to be part of the franchise; John Carpenter was hoping to turn it into a Thematic Series of standalone horror films, all set on Halloween. Had his plan succeeded, it seems quite likely that a lot of unrelated horror film scripts would have been dolled up as Halloween films, but three films in was too late to retool the franchise.
- Jaws 3-D started life as an unrelated shark exploitation screenplay that involved a shark swimming upstream and getting stuck in a lake, but was hurriedly reworked into the third entry in the Jaws series after the producers' original pitch — a spoof named Jaws 3, People 0 — was rejected by the studio.
- Journey to the Center of the Earth from 1989 started off as an In Name Only adaptation of the novel, but was never completed due to lack of funds. Albert Pyum came on board to make the film a sequel to his Alien from L.A., and burned off the unused footage in a dream sequence.
- The Haunted Palace was an adaptation of an H. P. Lovecraft story ("The Case of Charles Dexter Ward"), and was originally titled The Haunted Village. But because its director (Roger Corman) and star (Vincent Price) were better known for Edgar Allan Poe adaptations, the production company decreed that a few lines of Poe's poem be tacked onto the film, and the title changed to match.
- The Conqueror Worm, a historical drama that contains one of Vincent Price's best performances, is an even more egregious case: known as Witchfinder General in the U.K. (and in most subsequent rereleases), it was renamed for the American market and overdubbed with Price reading some lines of Poe's poem to seem to stitch it onto the Roger Corman series.
- Another, particularly shameless, example featuring Vincent Price: the German dub of the film Scream and Scream Again renamed his villain Dr. Browning as Dr. Mabuse, and marketed it as an installment in Germany's long-established Dr. Mabuse franchise.
- The 2004 film version of I, Robot was initially based on an unrelated screenplay, Hardwired, before being given the title and some surface features of the short story collection by Isaac Asimov. Granted, the dolling-up process did incorporate something like a Hollywoodized version of Asimov's Three Laws, and the final plot somewhat resembles a mish-mash of Asimov's "The Evitable Conflict" and The Caves of Steel. Still a painfully awkward fit with Asimov's stories, though, and nothing excuses making Susan Calvin into a hot young sidekick. (Contrary to what some have said, the film bears even less resemblance to Eando Binder's "I, Robot" than Asimov's story collection, except in the basic "robot kills someone" sense.)
- Lost Boys: The Tribe started out as a script about werewolf surfers called simply The Tribe - the plot was thought to be too similar to The Lost Boys, so it was rewritten into a sequel by replacing the werewolves with vampires and getting Corey Feldman to reprise his role as Edgar Frog plus Cory Haim as Sam Emerson in The Stinger. Some other Shout Outs and Continuity Nods to the original were also added, perhaps most notably a sequence using a Cover Version of "Cry Little Sister".
- Ocean's Twelve started out life as a stand-alone heist flick about two dueling master thieves that got the Ocean's Eleven gang shoehorned into it when the first film's massive popularity required a sequel as quick as possible. The role of the protagonist was split between Danny (master thief), Rusty (relationship with Europol agent), and (to a certain extent) Linus.
- The Rage: Carrie 2 was originally written as a standalone film titled The Curse. It was retitled and rewritten presumably because somebody pointed out the obvious similarities to Carrie and decided that calling it a sequel would not only allow it to cash in on the success of the original, but would help it avoid accusations of plagiarism.
- The DVD release of the '90s made-for-video movie Robot Wars (1993) (no relation to the TV show of the same name) calls it Robot Jox 2. It doesn't take place in the same universe as Robot Jox but has a similar look due to both being handled by the same effects company.
- Saw:
- Saw II was based on an old script that was turned down repeatedly for being "too violent" and eventually picked up because Saw was a big hit and the script had similarities. According to writer/director Darren Lynn Bousman, the finished product bears little resemblance to his original script beyond character names.
- Inverted when a script originally meant to be a Saw prequel was, due to lack of interest by the producers, altered into a stand alone movie, The Collector (2009).
- When A Shot in the Dark was adapted into a movie from a stage play (which was itself translated from French), the only seemingly Defective Detective Paul Sevigne was replaced with Peter Sellers' slapstick Detective Patsy, Jacques Clouseau. This sequel to The Pink Panther (1963) shares little more than the title and the premise with the play. The Artistic Title sequence of A Shot in the Dark also sets it aside from other movies in the series by featuring neither the cartoon panther nor the famous Instrumental Theme Tune (the movie has its own Instrumental Theme Tune).
- Robert Rodriguez once planned a stand-alone movie about kids going inside a video game, which he later turned into Spy Kids 3-D: Game Over. This should come as no surprise considering how the decidedly not spy-oriented premise was haphazardly shoehorned into the Spy Kids verse. In Italy, the film was promoted as Missione 3D: Game Over, without any hint it was part of the Spy Kids franchise, perhaps for the better.
- Hello Mary-Lou: Prom Night II was originally a film unrelated to the Prom Night franchise called The Haunting of Hamilton High before it was unlucky enough to get picked up by the original Prom Night's distributor, who realized that they had another prom-themed horror film on their hands, and retooled it to cash in on Prom Night's success.
- Starship Troopers had little to do with the novel on which it was allegedly based. The rights to the name were bought after the script was written.
- All of the sequels to Troll are In Name Only sequels. Troll 2 was originally titled Goblins, but for whatever reason, the distributors just slapped Troll 2 on the movie, despite the lack of trolls. There are also two moviesnote with the name Troll 3, neither of which has anything to do with the first two.
- Similarly, House III: The Horror Show was simply a haunting movie called The Horror Show, but the distributors wanted to cash in on the success of the first two films. That's why it's the only sequel without a pun title (e.g. House II: The Second Story, House IV: The Repossession). Ironically, both The Horror Show and House II were included among the Italian In Name Only sequels to The Evil Dead (1981), as parts 6 and 7. The Mockbuster parts 3 (as they were made before Army of Darkness) were released overseas with titles hiding those intentions - La Casa 3 became Ghosthouse, La Casa 4 (with David Hasselhoff and Linda Blair!) became Witchery and La Casa 5, Beyond Darkness.
- All of the Watchers "sequels" are, in fact, remakes (save for part 3). This makes a Watchers movie marathon an exercise in redundancy.
- The has become par the course for the Hellraiser film franchise, with the later straight-to-video releases being rather infamously made this way, chiefly to retain production rights. This extends to four or five out of the ten films in the series.
- According to Pinhead actor Doug Bradley, Hellraiser: Inferno is an example of this, and it has been noted by many the cenobites play a smaller part in this film than previous installments, but director Scott Derrickson has disputed this.
- Hellraiser: Deader was originally intended to be completely unrelated to the series, and the original screenwriter wasn't thrilled about it. There was a good bit of fan material on the disk related to it though.
- Hellraiser: Hellworld was originally a non-Hellraiser screenplay, which is why the final film deals relatively little with the cenobite characters.
- Rumor has it this is also the case with the ninth film, Hellraiser: Revelations - a panned film intended to secure the rights so Dimension Films could produce an ambitious remake.
- Hellraiser: Judgement could be called a "reunited installment", zigzagging this trope: series FX artist Gary J. Tunnicliffe first intended it as a Hellraiser film, but after rejections and scheduling conflicts when production was considered, he scrubbed the Hellraiser elements and took to KickStarter to fund it independently. When the studio needed to make another Hellraiser film anyway, they used this one since they already had it.
- Films in the Curse series have nothing to do with each other (aside from the body-horror element returning in at least part 2).
- The TV movie Malibu Shark Attack was re-titled for some DVD releases as Megashark In Malibu, with the tagline "the legend returns", presumably an attempt to cash in on the dubious fame of Mega Shark vs. Giant Octopus. To make things even more unusual, the title card in the film itself reads Shark Attack of the Malibu in this version.
- The Bruce Almighty sequel Evan Almighty was initially written as a completely separate script called The Passion of the Ark. After Universal spent a few million on the script, the script was reworked into a sequel due to the success of Bruce Almighty combined with Steve Carell's newfound fame. The final result shows that hasty rewrites occurred, as Evan was portrayed a much more sympathetic character compared to the first movie.
- Terry Gilliam's Jabberwocky was released in some areas as Monty Python's Jabberwocky. Half of the group had nothing to do with the film.
- Anchorman: The Legend of Ron Burgundy has a weird case with Wake Up, Ron Burgundy, a collection of alternate takes and a lengthy deleted subplot about terrorists from the original film, all cobbled together to feature length. The narrator sells it like it's a sequel, but it's obviously not.
- The script of an unproduced movie Big Baby was rewritten to be a sequel to Honey, I Shrunk the Kids, thus came Honey, I Blew Up the Kid.
- Mad Max: Beyond Thunderdome was first just an After the End film about a man meeting up with a colony of feral children. Then someone suggested that man should be Mad Max.
- Bruno Mattei's shark mockbuster Cruel Jaws is titled in some places Jaws 5: Cruel Jaws (then again, the film blatantly uses footage from Jaws and Jaws 2).
- The script to George of the Jungle was originally a spec script for a Tarzan parody called Gorilla Boy that writer Dana Olsen avoided sending in to Disney as he felt that the studio didn't want Dueling Movies. Olsen later found out that George of the Jungle didn't have a script so he sent Gorilla Boy to Disney, Disney liked it and Gorilla Boy became George of the Jungle.
- One alternative title for Memorial Valley Massacre turns into a sequel for Sleepaway Camp.
- Meatballs Part II was originally shot under the name Space Kid and was going to be more like Porky's than the first Meatballs. Then the film got picked up for distribution, the Meatballs name was applied and nearly all of the sexual content was cut to create a more family friendly film in the vein of the first. Of course, the two later films would end up becoming raunchier in an attempt to keep the franchise going.
- After the film Society bombed, the sequel's script was rewritten into Initiation: Silent Night, Deadly Night 4.
- In a remake's attempt to become a Divorced Installment, The Karate Kid (2010) was originally named The Kung-Fu Kid (since it's about kung fu, not karate), but Jackie Chan refused to do the movie unless it was renamed to increase its marketing appeal.
- 8mm 2 has nothing to do with 8mm. It doesn't even feature a video camera at any point, let alone an 8mm one. It was shot and produced as a boilerplate softcore erotic thriller (the kind you might see on Cinemax late at night). The 8mm name was tacked on in the 11th hour when the distributors got the rights to that movie, in a last-ditch attempt to make a profit on the film.
- The Raid 2: Berandal was actually written by Gareth Evans before the original The Raid. When The Raid became an international success, Evans simply dusted off his older script, and changed a couple of character names and rewrote the beginning so that the main character would be one of the surviving main characters from the earlier film.
- The Italian war movie The Last Hunter was originally sold as a sequel to The Deer Hunter, even though the two are remarkably dissimilar other than the Vietnam backdrop.
- Dracula Untold wasn't originally intended to be part of a new "monster universe", but the ending was altered to allow for this. Then it failed at the box office, so it didn't wind up starting one anyway.
- The Lords Of Flatbush was released in Italy as Happy Days - the Peach Flower Gang, giving the impression it was a prequel to Happy Days, even changing the name of Henry Winkler's character into "Fonzie".
- Rick Jaffa wrote the first treatment for Rise of the Planet of the Apes as an original story inspired by reports of people raising primates as children in their homes and being attacked by them. It wasn't until he was finishing it that he realized that, given enough time, the situation created by the ending could very well lead to the world seen in the 1968 Planet Of The Apes. So Jaffa contacted FOX, presented the story as a reboot for Planet of the Apes, and this is the result.
- The Direct to Video film Anything For Love was marketed as a sequel to Just One of the Guys in the United States, and Hes My Girl in Germany and Hungary (all three films feature a main character disguised as the opposite gender).
- The film Mind Ripper (aka The Outpost) is called The Hills Have Eyes 3 in some areas, since it has some involvement from Wes Craven, who directed the original The Hills Have Eyes (1977).
- Under Siege 2: Dark Territory was originally a standalone Steven Seagal action film called In Dark Territory.
- The Exorcist III was based on William Peter Blatty's unrelated book Legion and was an unrelated film until Warners decided to turn it into Exorcist III.
- The Falcon Takes Over, the third film in a series starring George Sanders as a detective called the Falcon, was an adaptation of Raymond Chandler's Philip Marlowe novel Farewell, My Lovely. Time to Kill starring Lloyd Nolan as Mike Shayne is actually an adaptation of another Marlowe novel, The High Window.
- In 1992, Peter Sagal wrote an original screenplay called Cuba Mine based on the real life experience of producer JoAnn Jansen, who lived in Cuba as a 15-year-old in 1958-59. It was about a young American woman who witnessed the Cuban revolution and had a romance with a young Cuban revolutionary. The screenplay was to be a serious political romance story, documenting, among other stories, how the Cuban revolution transformed from idealism to terror. A decade after gathering dust, it got turned into Dirty Dancing: Havana Nights. Seriously.
- After the success of Django, several spaghetti westerns were retitled (especially in Germany) to make them look like sequels to Django. He wasn't the only character to get this treatment: Johnny Ringo, Sartana and Sabata all got unofficial sequels. A list can be found here.
- Sometimes the name change didn't go beyond the title. For example in Kill Django...Kill First the hero is called Johnny Magee. And in Django kill, if you live...shoot! the main character has no name.
- Viva Django! did start out as a proper sequel for Django, but as Franco Nero was unavailable (he was starring in Camelot), the role was recast with Terence Hill. Subsequently the movie was marketed in the Netherlands as a sequel to They Call Me Trinity.
- Terence Hill also features in a cross-genre example. In 1970 Hill starred in a Spanish political drama called The Wind's Fierce, playing a strikebreaker hired by a Spanish mining company to infiltrate a radical union, growing sympathetic to the strikers and ultimately being killed by his employer. Not only was this movie released as a Trinity sequel in some markets, at least one Italian trailer tried to market the movie as a slapstick comedy!
- Yul Brynner's character in Adios, Sabata is called Indio Black in the original Italian version, however the name change actually makes sense in this case, since both Sabata and Adios, Sabata were directed by Gianfranco Parolini and Indio Black is exactly the same character as Sabata, only with a different costume.
- A particularly egregious example involves A Fistful of Dollars. An Italian distribution company which owned the rights to Clint Eastwood's series Rawhide edited several episodes of the show into a feature film which they titled The Magnificent Stranger (the Working Title of Fistful) and marketed as a sequel. Eastwood and CBS sued the distributors and Stranger was withdrawn after a brief theatrical run in Italy and West Germany.
- Bruno Mattei:
- Rats: Night of Terror was marketed in Germany as a sequel to Escape 2000.
- Shocking Dark, was originally marketed as a sequel to The Terminator under the title Terminator II. Hilariously, the actual plot has more in common with another James Cameron film, Aliens.
- Maciste was a stock hero of many Italian films, a superhuman strongman akin to Hercules. When his '60s Sword and Sandal pictures were dubbed for US distribution, the majority changed Maciste to someone more familiar to Americans—usually Hercules, sometimes Samson or Goliath—and altered the title to match. See, for example, Hercules Against the Moon Men.
- The Sons of Hercules was an attempt to repackage 13 Italian-made Sword and Sandal films (including a few about the above Maciste) for TV syndication in the U.S. by changing their protagonists into various sons of Hercules, presumably having adventures of their own once they reached manhood. Curiously, several of the original films were already about Hercules himself, and one of them - The Son of Hercules Against the Fire Monsters - had a Hollywood Prehistory setting, raising the question of how Hercules had a Handsome Heroic Caveman son who lived thousands of years before he did.
- Narrator: Through the centuries, in olden times, there lived: the Sons of Hercules! Heroes supreme!
Bill Corbett: Illegitimate as Hell!
- Werewolves on Wheels was billed as a sequel to Angels Hard as They Come in Australia, where they are billed as the Angel Warriors series.
- Trial and Error, a 1998 film with Jeff Daniels, was renamed Ancora più scemo ("Even Dumber") in Italy, just to capitalize on the success of Daniels' earlier film, Dumb and Dumber, which in Italy was named "Scemo e + scemo" (more or less an exact translation of the title). The two films are of course totally unrelated.
- Carry On:
- Carry On, Sergeant was based on the play The Bull Boys by R. F. Delderfield and was adapted into a script by Norman Hudis with John Antrobus contributing additional material and replacing the conscripted ballet dancers of the novel into a married couple.
- Carry On Nurse was based on the play Ring for Catty by Patrick Cargill and Jack Beale.
- Carry On Cabby was pitched as a stand-alone film named Call Me A Cab, but was changed in post-production.
- Carry On Jack started out as a script called Poopdecker R.N., but Peter Rogers, who owned the rights to James Mitchell's Steady Boys Steady, adapted it for Talbot Rothwell's script but it was quickly changed to Talbot's alternative Up the Armada, but the film censor thought it too lewd so it became a Carry On.
- Carry On Again Doctor raised problems with The Rank Organisation's legal adviser, who felt it was too similar to an unfilmed Doctor... Series script that Rothwell had previously submitted to producer Betty Box. Most notably, both scenarios featured the medical mission/slimming potion idea. As Box had not taken up the option on Rothwell's Doctor script, however, it was felt there were no legal problems with the use of those ideas in this film.
- The Awful British Sex Comedy Adventures of a Plumber's Mate was originally part of the Confessions of a... Series before it got cancelled. Adventures of a Private Eye was presumably adapted from the book in the particular series those films were based on, Confessions of a Private Dick.
- A minor case revolves around all the DC Comics films that languished in Development Hell before the DC Extended Universe made it easier to just develop them as part of the franchise, such as Wonder Woman and SHAZAM!.
- Timber Falls, being a movie about people going through horrible times in the woods, was released to made it seem related to Wrong Turn - ironically, the same year that movie got a sequel. In Brazil, Timber Falls came first and was billed as Wrong Turn 2, but in Mexico it arrived after Wrong Turn 2: Dead End and became Wrong Turn 3.
- A straight-to-DVD crime thriller was released in some Asian markets as Memento 2 despite the movies having nothing to do with one another.
- In the Netherlands, War Pigs was released as the fourth Saints and Soldiers movie. The only things the film has in common with the series are that it takes place in World War II and was directed by Ryan Little, who also helmed the trilogy.
- Martians Go Home was released in Italy as a sequel to Spaceballs.
- The obscure movie Stewardess School was released in Italy as the third Airplane! movie.
- Silent Running was released in Italy as 2002: The Second Odyssey.note
- The movie adaptation of Trent's Last Case was passed off in Italy as a sequel to The Third Man, trying to connect the two completely unrelated plots by exploiting the fact that Orson Welles appears in both films (main character in The Third Man, a cameo as the victim in Trent's Last Case) and adding the theme song from the earlier movie in multiple scenes.
- Pirates of the Caribbean: On Stranger Tides was based on the unrelated Tim Powers novel On Stranger Tides, and only reused some plot elements with Jack Sparrow and Hector Barbossa added in. That said, the novel was a major influence on The Secret of Monkey Island, which in turn was a major influence on the PotC films, so it's kind of a Recursive Adaptation.
- Ater The Elite Squad became a runaway illegal hit due to a Content Leak, the street-DVD piracy got some real films and labeled them as "Tropa de Elite 2" (a documentary about the war on traffic), "3" (actual BOPE images) and "4" (a Brazilian movie about the origins of drug-dealing group Comando Vermelho).
- Once Paul W.S. Anderson played Resident Evil, he wrote a script named Undead which he admitted to be a rip-off of the game. The production company seeking to adapt the series actually liked it enough to ask him to turn that into the actual Resident Evil movie over some more faithful scripts that were submitted. It was successful enough that it spawned several sequels, which tried to incorporate more characters and elements from the games.
- A What Could Have Been example: In the 1980s, Milton Subotsky of Amicus Productions was trying to sell a screenplay based on Guy N. Smith's Night of the Crabs. When he didn't get any takers, he reworked it into Doctor Who: The Ultimate Adventure (apparently shipping it around and asking The BBC about the rights simultaneously). This never got picked up either.
- Murder at the Gallop and Murder Most Foul are Margaret Rutherford Miss Marple films, based on the Hercule Poirot novels After the Funeral and Mrs. McGinty's Dead.
- Patrick Still Lives is an unauthorized In Name Only sequel to the 1978 Australian film Patrick. Beyond the name of the title character and him possessing Psychic Powers, the two are remarkably dissimilar.
- Supposedly, Howling II: Stirba: Werewolf Bitch was adapted from a spec script for a vampire movie completely unrelated to The Howling. This would explain why the movie's werewolves act a lot more like vampires and its plot connection to the first movie is extremely tenuous.
