Baby Face (1933)
We meet Lily in her father's speakeasy in industrial Pennsylvania, serving factory workers and a crooked politician, to whom her father occasionally pimps her out. Lily has two friends: a barmaid named Chico (Theresa Harris), and old Mr. Cragg, a Nietsche-reading cobbler (Alphonse Ethier), who advises her to use her natural abilities to exploit what men want to get what she wants. After the accidental death of her awful father, Lily runs off to New York City with Chico and gets to work on what she wants — financial security and fine things — starting at the personnel office of a large bank and eventually making her way to the penthouse.
Dashing young Courtland Trenholm (George Brent), the new bank president (you'll just have to see what happened to the old bank president) puts the kibosh on Lily's activities, but eventually finds her as enchanting as other men have before, and she's back on track.
At the time this film was made the Motion Picture Production Code was in place, but not rigidly enforced, and Baby Face was one of the pictures that kicked compliance into high gear. Reaction to the first release of the film caused such outrage that Warner Bros. had to recut it to tone done the "luridness" and tack on an ending more in keeping with the precepts of the Code.
