That Certain Age is a 1938 American musical film directed by Edward Ludwig and starring Deanna Durbin and Melvyn Douglas. Based on a story by F. Hugh Herbert, the film is about a dashing reporter who returns from covering the Spanish Civil War and is invited to spend time at his publisher's home, where his adolescent daughter develops a crush on him. The family does their best to sway the young girl's feelings away from the reporter, but it is a challenge, as she is at "that certain age".
