2026 marks the 70th anniversary of this suspenseful science-horror classic from legendary writer Jimmy Sangster. Often considered an unofficial part of the Quatermass franchise, the film makes its debut on Blu-ray and 4K UHD - the latest to be restored by the teams at Hammer and Silver Salt Restoration.

When a soldier dies from apparent radiation poisoning, the Atomic Energy Commission sends scientist Dr. Royston (Oscar-winner Dean Jagger) to investigate. Despite extensive testing no source can be found - until a mysterious radioactive, mud-like entity resurfaces and begins claiming more victims. What do you do when the killer can’t be stopped - or even understood?
