The first two adult orientated films I saw during the same year in 1961 were Saturday Night and Sunday Morning, and Room At The Top.
I was thirteen years old at the time, and found them both difficult to understand to be honest.
Since then I have rated both as classics of The British New Wave Cinema, now popularly known as Kitchen Sink Dramas.
And owning them both on DVD I still enjoy watching them today. They were pioneer flms at the time, exploring adult relationships more explicitly than before, although they look pretty tame today. But they have held up well because many of the actors who appeared in them have remained to this day some of the greatest actors of their generation:
Albert Finney; Laurence Harvey; Shirley Ann Field; Rachel Roberts; and the French actress Simone Signoret who was an incredibly sexy woman for her time.
One other adult film which I should mention and also rate as an all-time classic is the Alan Bates/June Ritchie drama A Kind Of Loving.
If some of you havent seen them, and who hasnt? Give them a try, it will give you an opportunity to see how adult films were made in those days.
