Writer-director Philip Dunne, collaborating with Edith Sommer on an adaptation of James Leo Herlihy and William Noble’s play, brings us Blue Denim (1959), an echt-Fifties “issue movie” about a pair of teenagers (Carol Lynley, Brandon de Wilde) who find themselves facing the horror of an unwed, unwanted pregnancy. These are “good kids,” for whom things go wrong, to the dismay of parents, friends, educators, all of whom, somehow, have failed to educate these children: babies having babies, indeed. Highlighted by a score from the singular Bernard Herrmann.
