British new wave

This British New Wave is an era of film making that I have been researching, as I feel it holds relevance to the effect I want to achieve when producing our own film.
The British New Wave is essentially a trend in British film making that began in the late 1950's early 60's. They are commonly referred to as 'kitchen sink dramas' because they focus on the reality of life for working class people, particularly in the north of England with films such as 'Saturday night Sunday morning'. These dramas focus on the gritty, everyday difficulties of average people which relates to our own short film because our idea is based on representing an average boy from a working class family and the troubles he encounters. The British New Wave predominately focuses on the issues that society upheld, that create a situation for the characters, through no fault of their own, where they are stuck in a rigid mould unable to move out of their class division, the 'ideal' lifestyle already laid out for them regardless of intelligence or determination. Films such as 'Saturday night Sunday morning' began to depict something very unheard of, dissatisfaction with the system and a desire to break free which relates to our own short film, as our protagonist is in denial, seemingly leading a happy successful life but instead trapped by the situations around him.
In comparison to today's film making, British new wave is very mild as now, nothing is off limits. I feel this is an interesting comparison because it so clearly shows the progression of society that I want to portray in our film, as it seems that as freedom grows, society's guidelines shrink and so therefore rebellion is ultimately supported, as can be noticed between the two films 'Saturday night Sunday morning' and 'This is England'.
Below is a 'Saturday night Sunday morning' film poster:

One play that provoked controversy and is an example of British new wave that I have been reading, is John Osbornes 'Look back in anger' written in just one month in 1956. When first published many didn't like the harsh reality portrayed through this piece, and possibly found it exceedingly difficult to accept the realistic, unfulfilled fate of many working class people unable to break the mould society created for them. 'Look back in anger' focuses on a love triangle revolving around 'Jimmy', a lower middle working class man who is eager to be free of exactly what is expected of him, and instead achieve what he wants to do. This play was considered shocking at the time because it spoke very bluntly of the lifestyle troubles, one particular memorable quote being when Jimmy says unaware of Alison's pregnancy; “If only something—something would happen to you, and wake you out of your beauty sleep! If you could have a child, and it would die. Let it grow, let a recognisable human face emerge from that little mass of India rubber and wrinkles. Please—if only I could watch you face that. I wonder if you might even become a recognisable human being yourself. But I doubt it.”. Life was very much rose tinted during this era, so it was unheard of to talk of such issues in such an abrupt, blunt manner.
Howard Brenton, writing in the Independent newspaper at the time of Osborne's death in 1994, said, “When somebody breaks the mould so comprehensively it's difficult to describe what it feels like”.
Below is a scene from the 1989 adaption of 'Look back in anger' that demonstrates the difficulties that were portrayed.
