This is considered to be the inaugural example of Straßenfilm ("Street Film") a sub-genre of films that flourished in Germany during the Weimar period and dealt with such subjects as urban blight, poverty, political corruption, and the underworld. Like this film, other Street Films were noted for mixing gritty realism with an expressionist approach to lighting, set design, acting, story structure, cinematography and editing. This genre would disappear with the rise of the Third Reich. The Street Film is credited with laying the groundwork for Film Noir in the United States, Italian Neorealism, and the cinema of the French New Wave.
