In case you've been living under a rock, the classic '90s show The Crystal Maze will return in October with a one-off special to raise money for Stand Up To Cancer.

And despite David Tennant being tipped to host the show, Channel 4 has FINALLY revealed that it will actually be Stephen Merchant that will present the one-off episode.

Confirming the news, the comedian said: "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.

"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 episode will be filmed at The Crystal Maze experience in London (which we loved, by the way), and will feature classic games as well as a few new ones.

The Crystal Maze originally aired between 1990 and 1995 and featured four different zones set in various periods of time and space.

Contestants competed in a series of physical and mental challenges in order to win crystals, which each gave five seconds of time inside the amazing final challenge, the Crystal Dome.

The Rocky Horror Picture Show's Richard O'Brien hosted The Crystal Maze when it was regularly pulling 4 to 6 million viewers. He was later replaced by Edward Tudor-Pole.
