Saturday Night and Sunday Morning was a 1960s film based on a book by Harry Sillitoe. The story featured a character named Arthur Seaton, who in the film was portrayed by Albert Finney. When Susan Foreman began reading it in 1963, Mr Grange of Coal Hill Secondary School confiscated it because she was meant to be studying Swiss crop-rotation.
When she went to see the film with Gillian Roberts on 30 March 1963, Susan still had not completed the book. However, as the film gained X ratings, she and Gillian were forced to dress up as adults to gain entry. Unfortunately for them, Ian Chesterton and Barbara Wright, both teachers at Coal Hill, went to the same showing. Knowing that they might reveal their true ages, the two children were forced to hide from them. (PROSE: Time and Relative)
