Perhaps the most famous original drama to emerge from the BBC dramatic anthology Theatre 625, The Unman, Wittering and Zigo Trilogy was spread out over three 75-minute episodes (which makes sense in the cast of a trilogy) in June of 1965. Peter Blythe starred as John Ebony, an idealistic young teacher assigned to one of the toughest and most dangerous comprehensive schools in England. The sullen students made no secret of their contempt for everyone over the age of 18, dropping not-so-subtle hints that Ebony's predecessor had been murdered. Before long, Ebony was smack in the middle of an agonizing mystery involving a student named Zigo, who never seemed to be present for the morning roll call. The three individual episodes were officially titled "Seek Her Out," "The Long House," and "Unman Wittering and Zigo." This last title was utilized when the property was streamlined and remade as a theatrical feature in 1971.
