O'Brien hosted the first four series of the enduringly popular game show

The Crystal Maze‘s original host Richard O’Brien is returning for the show’s upcoming charity special.

O’Brien, also known for creating The Rocky Horror Show, will not co-host the one-off revival episode with Stephen Merchant, but has recorded what is described as a “substantial cameo” for the special. The Radio Times reports that his guest appearance “has all the acid-tongued weirdness we’d come to love about the original series”.

Channel 4 recently shared the first picture from its upcoming Crystal Maze charity special. Merchant, sporting a shaved head in a nod to Richard O’Brien, will be joined in the one-off revival episode by celebrity contestants Sara Cox, Josh Widdicombe, Rio Ferdinand, Michelle Keegan and Sara Cox.

The Crystal Maze special will air on Sunday, October 16 at 9pm as part of Channel 4’s annual Stand Up To Cancer campaign. The creative team behind the episode have said that if it proves popular, a full series could follow.

“As a huge fan of the original series, I’m honoured to support Stand Up To Cancer by hosting this one-off edition of The Crystal Maze,” Merchant said when the episode was announced. “Richard O’Brien and Ed Tudor-Pole leave big shoes to fill, but I have size 14 feet, so I’ll do my best.”

The Channel 4 show originally ran for 83 episodes between 1990 and 1995, with the first four series hosted by Richard O’Brien, and the final two steered by Tenpole Tudor frontman Edward Tudor-Pole.

A live immersive version of the game show opened in London earlier this year. See how the NME team did here.
