After making Thieves Highway in 1949 Jules Dassin was blacklisted for being a communist. The movie is about working class men -- Army vets at that -- trying to use capitalism to pull one over on a small-time robber baron, and when that fails there's some violence. It's not quite Marx, but it's not quite not Marx.
Anyway, Dassin would flee to Europe and continue working, first with Night and the City which we'll talk about next week, and later with Rififi, his masterpiece.
