Jules Dassin's last film in America, 1949's Thieves' Highway, is a very good movie.
Jules Dassin's first film in France, 1955's Rififi, is one of the best movies.
But in between, in 1950, Dassin's path in life took him through London where he made Night and the City. On the one hand Dassin could make a noir film in his sleep, on the other, with Night and the City, he did. The director claims he never even read the script, and in many ways it feels like someone tried to make The Third Man from memory without a very good memory.
