At the end of the 1960’s, a lot of US studios started pulling out from producing films in the UK. Some were still investing in films in the UK, but things had started shifting back over to Hollywood thanks to the New Hollywood movement. However, with the exit of a lot of US studios, the UK lightened up their rating restrictions and this brought a lot of filmmakers to a prominent rise in the UK. The lightened restrictions added additional perks for young American directors to take their productions to the UK as well.
Generally, 70s British cinema is looked down upon due to it’s decline in viewers and mainstream attraction. Viewers in the UK were unlike the movie crazed kids of the 70s in America, in fact they were more attracted to television. But, this allowed for more experimentation in cinema. A long with the lightened censorship, the early 1970s British cinema introduced some of the most explicitly violent and controversial films of all time.
