The Crystal Maze S00 E01 Christmas Special 1

Richard O'Brien stars as the Maze Master in a Christmas Special, leading a team of six young adventurers (Christine, Deborah, John, William, Catherine and Michael) around the eponymous Crystal Maze, in search of time crystals that will ultimately lead to the Crystal Dome and a chance of winning the star prize. NB: Michael Underwood would later go on to host Jungle Run, a childrens TV show very heavily based on the concept of the Crystal Maze.
