Mother (1996)

A writer believes the key to solving his many troubles with the opposite sex can be found by retracing the steps of his youth. Science-fiction scribe John Henderson (Albert Brooks) can't find a solid relationship, so he moves back in with his mother, Beatrice (Debbie Reynolds). John means well, and he seems to genuinely believe that a better understanding of his mom will lead to dating success. But when they begin to bicker, both start rethinking the arrangement.
