Kidulthood ($920,000 budget)
Kidulthood is a 2006 film by Noel Clarke which gave its audience a glimpse into the lives of poor and lower-class citizens living in West London. It’s a well-known fact that independent films in the UK struggle to get funding, but Kidulthood did, and it made over $2 million at the box office.
The film’s success led to the creation of the sequel, Adulthood in 2008, and the third and final film Brotherhood was released in 2016.
