Catacombs (U.S. title: The Woman Who Wouldn't Die) is a 1965 British horror film directed by Gordon Hessler and starring Gary Merrill, Georgina Cookson and Jane Merrow.

An astute business woman is murdered by her husband who intends to carry on with his affair with her niece after her death.

[3] The Monthly Film Bulletin wrote: "One would have thought that the days of the murder story with the corpse buried in the potting-shed were long over, but the situation is revived here not entirely without effect.

The preliminaries setting the domestic scene are much too long, but after the murder things perk up considerably, with one or two nice macabre effects.

"[4] Variety wrote: "What could have easily been on of those quickie, murder-on-the-moors thrillers which the British seem to turn out over a weekend, this Jack Parsons production comes off something better than average because of a very good performance by Georgina Cookson and taut direction by Gordon Hessler of Dan Mainwaring's spare but neat screenplay.
