The Children's Film Unit was formed in 1981 by schoolteacher and ex-Avengers writer, Colin Finbow.[3][4] It had begun life as the film studies department at Forest Hill School in South East London. The standard of the work Finbow and his students produced so excited professional film makers due to its quality and freshness that, after one of their films, "The Custard Boys" (1979) received critical acclaim, it was suggested that more children should benefit from this unique experience.[5]
