The Brain That Wouldnt Die (1962)

Love is a many-splattered thing when a brilliant surgeon keeps the decapitated head of his fiancee alive after an auto accident while he searches for a suitably stacked body onto which to transplant the head. Absurd and satiric (head talks so much that Doc tapes her/its mouth shut) adding up to major entry in trash film genre; much of the gore was slashed for the video, however.
