Writer Giles Cooper's Unman, Wittering and Zigo was first presented as a BBC TV drama in the 1960s, which later was telecast in the US on NET Playhouse. David Hemmings plays the new teacher in a macabre classroom where the boys seem demonically recalcitrant. Just after calling roll (Unman, Wittering and Zigo are the last names on the tally), Hemmings is advised by his class that he'd better leave them alone to do as they wish. Hemmings' predecessor had not heeded this warning, and ended up dying a rather nasty death.
