Answer:
The answer is Italian Neo-Realism.
Explanation:
This movement arose after the end of World War II. These films focused on themes such as poverty and crime, and attempted a naturalistic portrayal of the low-life conditions of the post-war Italy.
This movement eventually inspired other alternative filmmaking styles, such as the french nouvelle-vague (New Wave), and even some contemporary filmmakers like Martin Scorsese have quoted Italian Neo-Realism as a source of inspiration.
