This early offering from the studio that would go on to become the greatest force horror would ever see lacks the vibrant colours and pseudo-Gothic style that would go on to epitomise their later output, but it retains the British charm and wit that Hammer became famous for. The film also succeeds in being entertaining, and that’s what Hammer Horror has always done best. X the Unknown is your classic 50’s B-movie, and it follows a seemingly bottomless crack that has opened up in the Earth. This is not all, as adding to the Earth’s woes is the creatures that have come out of this pit; which are made of mud and feed on energy. For the time it was made, the effects certainly aren’t bad and this was an obvious blueprint for several b-movie ‘classics’, including most notably; The Blob. Seeing the huge mud creature fumble over telephone lines and rooftops is very fun to watch, and is a good early indicator of the sort of film that Hammer studios would go on to mass-produce.

One thing that X the Unknown is notable for is the believability regarding the scientists researching the ‘creature’. Too often in this sort of film, the scientists realise what is going on and everyone just accepts it, no matter how ridiculous it is; but here there’s a bit of opposition and it’s nice to see. The film remains interesting throughout thanks to the way that the plot is developed, and the fact that it doesn’t go over the top with detail. It attacks the premise from lots of different angles, and seeing the army do it’s best to thwart the creature is always amusing. The cast keeps the film afloat at all times, and the acting isn’t bad at all; and certainly much better than I was expecting. Most of the cast are unknowns, but one standout is Hammer regular – Michael Ripper, who puts in a small appearance. X the Unknown isn’t a brilliant film, and Hammer would go on to better this ten fold; but it’s good for what it’s worth, and I definitely recommend this movie to fans of classic ‘B’ cinema.
