Desc: Diane of the Follies: Directed by Christy Cabanne. With Lillian Gish, Sam De Grasse, Howard Gaye, Lillian Langdon. Phillips Christy, a strait-laced amateur sociologist from a wealthy family, subscribes to the theory that people are shaped by their environments. When he fall in love with Diane, a showgirl from the Follies, he sees a chance to prove that his theory is correct: he will marry her and mold her to be "cultured" and "sophisticated." However, fate intervenes to put a crimp in his plans.
