Although Hammer was best known for horror films, their entry into horror actually came by way of science fiction. Up until the 1950s, Hammer was pretty much your average low-to-medium budget production house, cranking out a lot of comedies, adventure, and war films. In 1955, however, the studio released a film featuring a popular sci-fi television series character by the name of Professor Quatermass. The movie, known as either The Quatermass Xperiment or The Creeping Unknown, was a blend of science fiction and horror, as was popular at the time, and it ended up being a big hit for Hammer. Encouraged by the film’s success, they dabbled in a few more sci-fi horror films, including X: The Unknown in 1956 and a second Quatermass film, Enemy from Space, in 1957. Like The Creeping Unknown, both of these films featured elements of sci-fi and horror. But then the studio released Curse of Frankenstein, Horror of Dracula, and The Mummy in quick succession, and before you could blink twice, Hammer was the House of Horror. Their previous, largely successful forays into science fiction were all but forgotten as the studio repurposed itself to produce almost nothing but Gothic horror films for the next decade. Eventually though, even Hammer couldn’t ignore that the space race had sparked interest in science fiction.
