* CareerResurrection: After a long period of dormancy, the Hammer film company (and Exclusive Film Distribution) was revived in 2007, with Dutch media tycoon John de Mol helping form it and Simon Oakes serving as its CEO and owner. This new Hammer would go on to produce several newer horror hits like ''Film/LetMeIn'' and ''Film/TheWomanInBlack'', even outlasting its former subsidiary.[[note]]Exclusive Media was sold and folded into [=AMBI=] Distribution in 2016, but Hammer is still active in the hands of Oakes.[[/note]]
* DivorcedInstallment:
** ''The Kiss of the Vampire'' was meant to be the third ''Dracula'' film in an attempt to make a film without Creator/ChristopherLee.
** ''X the Unknown'' was supposed to part of the ''Franchise/{{Quatermass}}'' series but, like ''The Kiss of the Vampire,'' ended up being a standalone.
* EnforcedMethodActing:
** Creator/ChristopherLee had an extreme phobia about spiders, so in ''Literature/TheHoundOfTheBaskervilles'', when the tarantula is crawling up his arm, he's not really "acting" terrified.
** Creator/NastassjaKinski was having trouble coming up with tears for a scene in ''To the Devil... A Daughter'' (she was very young and inexperienced at the time), so costar Creator/RichardWidmark straight-up ''slapped her in the face'' to get her crying. (Kinski, for her part, never bore him any ill will and said later she knew he was just trying to get a good performance out of her, and that he taught her a lot.)
* FakeNationality: About one million times. Basically, this would show up in any movie set outside England, and even some set ''inside'' it.
* MissingEpisode: Creator/HazelCourt allowed a topless scene to be filmed for 1959's ''The Man Who Could Cheat Death''. It was only included in prints distributed outside the U.S. and England. It appears this footage has been lost forever, although Court did put a still from it in her autobiography. (Let it never be said that she didn't appreciate her fans).
* TheOtherDarrin:
** Creator/ChristopherLee declined to play Dracula in ''Film/TheLegendOfThe7GoldenVampires'', partially due to fears of typecasting and partially because he thought the script was dreadful. John Forbes-Robinson replaced him.
** Neither Creator/IngridPitt nor Creator/PeterCushing returned for ''Film/TheVampireLovers''' sequel ''Film/LustForAVampire''. Their roles were played by Creator/YutteStensgaard and Ralph Bates.
* StillbornFranchise:
** The film version of ''Literature/TheHoundOfTheBaskervilles'' was meant to be the first in a series of films starring Creator/PeterCushing as The Great Detective. Alas, the British public weren't interested in a Hammer film with no monster and the idea was dropped.
** ''Film/CaptainKronosVampireHunter'' was meant from the start to be the first film of a franchise which would feature Kronos fighting a different species of vampires in each installment, but distribution issues resulted in a StillbornFranchise that wasn't resurrected until decades later when a comic book continuation was published.
* TroubledProduction: Verging on TheProductionCurse. ''Film/BloodFromTheMummysTomb'', adapted from Creator/BramStoker's novel ''Literature/TheJewelOfSevenStars''; Creator/PeterCushing was cast as the lead but had to drop out after a single day's filming due to the hospitalization of his wife. Then five weeks into production (with only one week to go), director Seth Holt had a heart attack and died (some reports saying this was ''on set'') and was replaced by Michael Carreras. On top of all that, star Creator/ValerieLeon was devastated when she was told she couldn't attend Holt's funeral. reporting on this, Magazine/ForteanTimes noted all the above and added that one scene in the film involved filming the aftermath of a motorcyle accident and the retrieval of a corpse from the scene. A member of the production crew died in a motorcycle accident just as filming got to this point.
* WhatCouldHaveBeen:
** In the mid-70s, Hammer was in talks of collaborating with Creator/{{Toho}} on producing a film about the Loch Ness Monster.
** They were interested in remaking ''Film/KingKong1933'' in the 60s but were denied by the studio that held the rights having a then "no remake" policy.
** Screenwriter Anthony Hinds was pushing for a film called ''The Unquenchable Thirst of Dracula'' as early as 1972 and as late as 1977 but it was ultimately never made. Hinds's script saw Dracula relocating to India during the 1930s and teaming up with a murderous cult, an idea which may have inspired his trip to China in ''Film/TheLegendOfThe7GoldenVampires''. Interestingly this film would have featured an ActionGirl as the main protagonist, a DownerEnding, and a complete lack of an experienced Van Helsing type of character to explain things, all major departures from the norm for Hammer. The script was eventually adapted as BBC Radio drama in 2017.
** Hammer was in negotiations with Warren Publishing and American Pictures International to produce a film version of ComicBook/{{Vampirella}} starring Barbara Leigh but it ultimately fell through. Depending on who you ask either Hammer wasn't able to put up their share of the budget or [=AIP=] was making demands they couldn't agree to.
** A mysterious unmade project called ''Zeppelin v. Pterodactyls'' appears to have been a UsefulNotes/WorldWarII-era dinosaur film. It never got beyond an early piece of poster art. Its believed to have been stop motion, or at least use the method for the titular dinosaurs; considering the film was to be an homage to the works of Willis O'Brien this seems likely.
** They contemplated a film adaptation of ''Literature/IAmLegend'' under the title of ''The Night Creatures'', written by Creator/RichardMatheson himself. The project was ultimately deemed too graphic, foundered and eventually died.
** Creator/JulieChristie was contracted to star in the thriller ''Nightmare'', but she begged Hammer to let her go so she could make ''Film/BillyLiar''. They relented and cast Jennie Linden instead.
** At one time they planned on creating a television series based on Frankenstein (with a new actor replacing Cushing) to be called ''Tales of Frankenstein''. It was to be a co-production with Columbia Pictures (which, as a subsidiary of Universal, meant they were granted permission to use the iconic Karloff makeup). A pilot, titled "The Face in the Tombstone Mirror" was filmed and screened for the executives of the ABC network, who like what they saw. More scripts were ordered, but Columbia rejected them all. This, combined with conflict between Hammer and Columbia executives over creative control, caused the project to fizzle out, although the pilot is available online and on DVD by Scream Factory.
