Scarlet Street 
The story follows a banker and aspiring painter, played to perfection by Edward G. Robinson, who saves a young woman from a purse snatcher one night while on his way home from a party. The two begin talking to each other, and the banker 'accidentally' tells the girl that he's paints pictures and gets a lot of money for doing so (Lang shows us the pitfalls of trying to impress young women by way of lies). However, all was not what it seemed with the purse-snatcher, and he's actually the young lady's fiancé; and when he learns that his girlfriend has a man with money after her.... he's out for all he can get! German director Fritz Lang is best known for the highly influential films from relatively early in his career, especially Metropolis (1927) and M (1931). But he also had a brief Hollywood heyday during the mid 1940s, when he made some of his best films. Scarlet Street has been claimed by film noir. This attribution is understandable. The lighting is dark, with heavy use of shadows. The characters are all shady as well.
