There is a film in which a man keeps his fiancee’s decapitated head, but he wants to find a body to affix it to:
The Brain That Wouldn’t Die (1962)
IMDb synopsis:
Brilliant but borderline psychotic surgeon (Herb (Jason) Evers) does secretive, experimental work with limb transplants and tissue rejection drugs, much to the chagrin of his surgeon-father (Bruce Brighton). When he crashes his car and his fiancee (Virginia Leith) is decapitated, his research – far from complete – is put to the test. His focus then becomes finding an appropriate donor body to make his fiancee whole, while the current and failed experiments in his basement laboratory grow restless.
Here’s the movie trailer:

This is the inspiration for the parody “The Man With Two Brains”, starring Steve Martin as the brain surgeon.
