Accent on Youth (1935)

Steven Gaye, a successful New York playwright has passed forty and thinks he has bid farewell to the world of romance. But he falls in love with his secretary, Linda Brown, and suddenly finds himself more madly in love than ever before in his life. Linda reciprocates his feelings but he feels there is a too wide gap in their ages, and he pushes her in the direction of the leading man, Dick Reynolds, in his current Broadway play. Linda becomes engaged to the younger man and finds there is a problem...while Dick is young and romantic, he is also dumb. And the longer Linda is with him, the more she yearns for Steven's comfortable understanding and mature charm. (Despite the site-plot line that says so, she does not marry the son of her boss.)
