The British/American co-production My Lover, My Son stars Romy Schneider as Frances, the unhappy wife of businessman Robert (Donald Houston). When her lover is accidentally drowned, Frances turns to her teenaged son James (Dennis Waterman) for comfort. Her husband doesn't like this set-up and bundles James off to college, but upon his return the boy enters into an affair with his own mother. Robert discovers the incestuous couple in an embrace and reacts violently, whereupon Frances kills him in self defense. Knocked unconscious during the struggle, James thinks he is the killer and takes the rap. The boy is released on the grounds of self defense and returns to his mother -- only to renounce her when he discovers that he's the illegitimate son of his mother's dead lover. MGM was the American distributor for My Lover, My Son, and that low vibration you feel is Louis B. Mayer spinning in his grave.
