The Tyrant King is a six-part children's serial drama directed by Mike Hodges, made by ABC Weekend TV and screened by Thames Television in 1968. It was dramatised from the book of the same name by Aylmer Hall, adapted for television by Trevor Preston. It was notable for its use of a progressive music soundtrack, including music from The Rolling Stones, The Moody Blues, Cream, Pink Floyd, and in particular, The Nice, whose song "The Thoughts of Emerlist Davjack", from the album of the same name was the title track.
The series was shot entirely on film, as opposed to videotape, and almost entirely on location throughout London; it served as the pilot project for what became Thames' TV film production unit Euston Films.
The story begins with three children overhearing a mysterious conversation, leading them to follow the clues across the tourist attractions of London.
The credits note that the three juvenile leads are "Pupils of Italia Conti Stage School."
