“The Man Who Knew Too Much and The Thirty-Nine Steps initiate a series of thrillers of which The Lady Vanishes (1938) is the most celebrated, but which also includes The Secret Agent (1936), Sabotage (1936) and Young and Innocent (1937). Young and Innocent displaces our interest from its unsympathetic male lead to its female protagonist, who is played not by an adult actress but by a real ‘girl on the threshold of womanhood,' the sixteen-year old Nova Pilbeam. It places this young and innocent girl within the setting of her bourgeois home, enabling The Lodger's conflict between romance and family to resurface.... Along with this shift, Young and Innocent reduces the role of the villain--he is not a theatrical genius like the Professor of The Thirty-Nine Steps but a decidedly ordinary man driven to distraction--and makes the camera a prominent agency within the world of film.” --William Rothman
