Terry Jones (b. 1942) is an actor and writer best remembered as a member of the Monty Python comedy troupe. In later years, he also became famous for his irreverent historical documentaries that primarily focus on medieval Europe.
Speaking to Kim Howard Johnson in Starlog #148 (November 1989), Jones recalls that he'd called Jim Henson for help writing the script for The Saga of Erik the Viking. During the call, Henson asked Jones if he'd be interested in writing a script for Labyrinth.
