1956 Sci-Fi Horror X the Unknown Returns in Stunning 4K for 70th Anniversary
The 1956 sci-fi horror classic X the Unknown is turning 70—and fans can now experience it in 4K for the first time. Directed by Leslie Norman, the film follows Dr. Royston, played by Dean Jagger, as he battles a mysterious, radioactive creature. A special collector’s edition arrives in the UK on July 13, 2026, packed with extras and multiple versions of the film. The story begins when a series of deaths linked to radioactive exposure leads to a terrifying discovery. Deep in an air shaft, workers uncover a deadly creature that feeds on radiation. Dr. Royston must race against time to stop it before more lives are lost.
The 70th-anniversary release comes in two formats. The **Limited Collector’s Edition** includes three cuts of the film across two Ultra HD Blu-rays and two standard Blu-rays. Extras feature newly recorded audio commentaries, a short film, documentaries, and an archive interview with screenwriter Jimmy Sangster. The set also comes with a companion book, eight art cards, and a double-sided theatrical poster—all housed in a leather-textured slipcase. For those seeking a simpler option, a **standard edition** will be available without the bonus materials or Blu-ray discs. Both versions offer English audio in mono and 5.1, along with subtitles in multiple languages, including German.
The 4K restoration marks the film’s first global Ultra HD release, giving audiences a chance to revisit—or discover—this British horror gem. With its mix of sci-fi tension and Cold War-era fears, X the Unknown remains a standout in 1950s cinema. The collector’s edition arrives in UK stores on July 13, 2026.
