The Thing that Couldn't Die is a 1958 American horror film produced and directed by Will Cowan and starring William Reynolds, Andra Martin, Jeffrey Stone, and Carolyn Kearney.

Based on an original screenplay by David Duncan for Universal Pictures, it was released in the United States on a double bill in May 1958[1] with the British Hammer Films classic Horror of Dracula.

Jessica Burns (Carolyn Kearney), a young woman who claims to have psychic powers, lives on a California dude ranch with her Aunt Flavia (Peggy Converse).

However, Flavia’s greedy ranch foreman, Boyd, also anticipating treasure, secretly convinces slow-witted handyman Mike to break the cask open.

Instead of gold or gemstones, the box contains the intact head of Gideon Drew (Robin Hughes), a man executed for sorcery 400 years earlier.

Reading text engraved on the box’s corroded metal surface, Julian and Gordon discover the existence of a coffin also buried on the property that contains Drew’s body.
