In 1991, Richard O'Brien wanted to leave as presenter of The Crystal Maze at the end of Series 3 but was persuaded to present one more series, and he agreed. Richard's last series, Series 4, was to feature the new Ocean World Zone which replaced the Industrial Zone. Richard felt he had 4 films he wanted to make, and never thought he would go down this sort of byway according to an interview. In the last episode of the 4th series there was no indication that he was leaving, so it was kept a scret right until this 1993 Christmas Special. He did agree to film a cameo role for this episode where he signed off and "left a note" for the new custodian of The Crystal Maze so him and Mumsey could "emigrate to America". 23 years later in 2016, Richard appeared in a cameo for the Stand Up To Cancer episode telling Stephen Merchant to not muck the game up. He appeared on the computer screen in the Futuristic Zone.
