Final answer:
Film noir was influenced by French Poetic Realism, a movement that provided a stylized and moody atmosphere akin to film noir's thematic and visual style.
Step-by-step explanation:
In addition to German Expressionism, film noir was significantly influenced by French Poetic Realism. This film movement emerged in the 1930s and included directors like Jean Renoir and Marcel Carné, who created films that blended the grittiness of everyday life with more stylized aesthetic elements. This approach to filmmaking greatly influenced the visual style and narrative themes of film noir, which often include moral ambiguity, complex characters, and a dark, moody atmosphere akin to what French Poetic Realism offered.
Unlike the later French New Wave and Italian Neorealism, which emerged post-World War II, or the Soviet Montage, which was known for its revolutionary editing techniques, French Poetic Realism had a more direct stylistic impact on film noir's formative years.
