There is considerable overlap between the New Wave and the angry young men, those artists in British theatre and film such as playwright John Osborne and director Tony Richardson, who challenged the social status quo. Their work drew attention to the reality of life for the working classes, especially in the North of England, often characterised as "It's grim up north". This particular type of drama, centred on class and the nitty-gritty of day-to-day life, was also known as kitchen sink realism.[4]
