The Crystal Maze is making its return with presenter Richard Ayoade, who will be joined by Adam Buxton and Jessica Hynes in cameo roles.
Adam Buxton will be setting the contestants on the quest for crystals riddles in the Futuristic Zone as a disembodied head called, appropriately, Jarhead.
Meanwhile Jessica Hynes will be on guard at the Medieval Zone, resplendent in armour reminiscent of the Middle Ages. Contestants will have to get past the Up The Women star who will defend the realm.
The first team set to try and beat the maze will be celebrity contestants Ore Oduba, Vicky Pattison, Alex Brooker, Lydia Bright and Louie Spence. The team are fundraising for Stand Up To Cancer.
You can catch the new series of The Crystal Maze on Friday 23rd June, 9pm on Channel 4.
