Kiss Me Goodbye (1982)

Kay (Sally Field) is a widow who's met a handsome but otherwise dull Egyptologist named Rupert (Jeff Bridges) and hopes to marry. Trouble is, the ghost of her dead husband, Jolly (James Caan), strenuously objects. A former Broadway director, he's visible only to Kay, and begins interfering in her life so much that others question her sanity. Jolly, however, cares only about driving away the hated Rupert, who for his part thinks to stage an exorcism.
