PREVIEW: Celebrity Crystal Maze, Channel 4

Richard Ayoade returns to guide more celebrity adventurers on an epic quest through the four fantastical zones of The Crystal Maze - Aztec, Industrial, Futuristic and Eastern - in a brand new series.

Within the zones, the teams face a host of Skill, Physical, Mystery and Mental challenges in a bid to win precious crystals, which they will exchange for time in the legendary Crystal Dome.

This time, TV presenter Laura Whitmore captains her team - comedian Chris Ramsey, dancers Perri Kiely and Jordan Banjo, and former rugby player Gareth Thomas - through the maze.

Celebrity Crystal Maze returns Thursday 03rd December at 10pm on Channel 4.
