From the video case: British Commandos on maneuvers near a muddy marsh become ill with mysterious symptoms and horrific burns. Dr. Royston (Dean Jagger), an atomic scientist from a nearby research station suspects lethal radiation but is mystified by the cause. At a nearby hospital, the phenomenon reappears and engulfs more innocent people including a hospital orderly whose skin has melted away from his body.
Dr. Royston speculates that the unknown force is on a quest to absorb radiation and expands in size and range as it claims more and more victims. As time runs short, he becomes desperate to trap the force before its power overcomes mankind. (1956, b&w)
Mark says: Hammer Film Productions had such success with their first Quatermass movie, The Quatermass Xperiment (USA title: The Creeping Unknown) that they were eager to produce a sequel. However, the author/creator of the Quatermass character, Nigel Kneale, denied Hammer any unauthorized use of his creation.
Instead, Hammer employed first-time screenwriter, Jimmy Sangster (who would later become a regular Hammer scriptwriter) to pen a movie in the Quatermass tradition, without actually using Professor Quatermass’s name. The result was X the Unknown, with Dean Jagger (Revolt of the Zombies) playing the role of the Quatermass equivalent, Dr. Royston.
