Social Realism is an genre, which is often used by the film company Warp, that produced this film. The genre is based on real life and even though the story's are mostly fiction, the stories are supposed to show a reflection of the world we live in.
The characters, dialogue and the entire mise-en-scene are all used and inspired by the real world.
The film opening from "This is England" is very useful when looking for a good example of the social realism genre.
The film opening also represents a lot of historical context. It shows many uprisings and demonstrations on the streets. People going on strike, wars and bombing of houses and ships etc. During many different clips we also see images of Margaret Thatcher, who was the prime minister of the United Kingdom from 1979 to 1990. By knowing this, we can state that a lot of the scenes may have been shot at that time period.
During the entire film opening, there are people and stories portrayed on screen. These show everyday characters and their working class backgrounds. This use of untrained actors and everyday situations, is a typical convention of a social realist film. It also makes the movie more realistic and the audience might also be able to relate themselves to the movie.
We also see a lot of different shots from the wedding of the Prince of Wales and Princess Diana, which took place on the 29th of July 1981. These pictures again show the audience that most of the scenes are shot in that specific time period.
A lot of scenes are emphasising on what Britain was like back then. The non-diegetic song in the film opening is called "54-56 What's my number?". The band "Toots and the Maytals", has written this song to show the ability to grow and thrive against injustice.
During the film opening, we see a lot of shots of demonstrations and also people fighting against the police. Since the song is about fighting injustice, we can conclude that many of the scenes were about people who felt unjust.
