The television show was based on four of The Demon Headmaster novels by Gillian Cross. The scripts were written by Helen Cresswell. The first three episodes of series one were adapted from the first book, The Demon Headmaster, and episodes 4–6 were adapted from the second book in the series, The Demon Headmaster and the Prime Minister’s Brain.

The development of the subsequent stories was more unusual: the second television series was The Demon Headmaster Strikes Again, and the third was The Demon Headmaster Takes Over. Gillian Cross wrote the storylines for each project, and then wrote the books; Helen Cresswell turned the storylines into screenplays. However, this is the director’s memory of events.
