St Trinian's is a fictional girls' boarding school, the creation of English cartoonist Ronald Searle, that later became the subject of a popular series of comedy films. The first cartoon appeared in 1941, but shortly afterwards Searle had to fulfil his military service where he was captured at Singapore and spent the rest of the war as a prisoner of the Japanese. After the war, in 1946 he started making new cartoons about the girls, but the content was a lot darker in comparison with the previous years.
