Social realism in film originated from Italian Neorealism after World War 2, which depicted the difficult lives of the working class. It was influenced by British documentaries of the 1930s and focused on location shooting in run-down urban areas. Key characteristics include using non-professional actors, close-ups to elicit sympathy, and exploring social issues like poverty, unemployment and injustice through working-class protagonists in dysfunctional family settings. Cathy Come Home, a 1966 BBC documentary-style series about a couple made homeless, had a huge impact and sparked political discussion.
