Produced by HTV, Into the Labyrinth ran for three seasons on ITV between May 1981 and September 1982.
Created by Peter Graham Scott and Bob Baker, the first season of the children's drama saw three children having to free the imprisoned wizard Rothgo (Ron Moody) and help him to regain the Nidus, which allowed him to focus his powers, and which had been taken by the evil Belor (Pamela Salem). Each episode therefore saw Phil, Helen and Terry transported to a different period in time to recapture the stolen artefact which was disguised as a different item in each time period.
Bob Baker is now best known for writing the scripts to The Wrong Trousers, A Close Shave and Wallace and Gromit and the Curse of the Were-rabbit — the three Wallace and Gromit adventures to have won Oscars. In the world of television science fiction he is probably best known for writing eight rather mediocre Doctor Who stories with Dave Martin, as well as Nightmare of Eden which he wrote on his own. Their 1977 story The Invisble Enemy saw the debut of K9. They also wrote the well-remembered children's telefantasy serials Sky and King of the Castle for ITV.
Season Two followed a similar path to Season One as Belor managed to split the Nidus into segments by using the Albedo, and then scatter them throughout time. Once again the three intrepid adventurers went on a voyage through time to collect the segments. Ironically, this is a very similar premise to Season Sixteen of Doctor Who in which the Doctor and Romana had to collect the six segments of the Key to Time which were scattered throughout time and space. The final story of that season was The Armageddon Factor, written by Bob Baker and Dave Martin...
Season Three saw a change in the series as Rothgo was replaced by Lazlo (Chris Harris), Phil was sent on the quest all by himself, and the Nidus was replaced by the equally powerful Scarabeus.
Of the three seven-episode seasons produced, only Season One has ever been commercially released, and that was on video in the early 1990s, with the episodes split over two seperate tapes.
