Celebrity Christmas Special: Ellie Simmonds, Nicola Adams, Ollie Locke, Mollie King, Tom Davis

Maze Master Richard Ayoade guides a team of intrepid celebrity adventurers around the mighty maze in this fiendishly fun festive special in aid of Stand Up To Cancer. The Aztec, Medieval, Industrial and Futuristic zones have all been dramatically transformed for Christmas. The Knight is clearly desperate for an invite for the holiday season, Jarhead has already been on the sherry and Richard has to contend with a group of carol singers who have double booked the maze for rehearsals. Gold medal-winning Olympians Ellie Simmonds and Nicola Adams, Made in Chelsea's Ollie Locke, The Saturdays and Strictly star Mollie King, and Murder in Successville comedian Tom Davis all form the tinsel-tastic team of stars hoping to win crystals to buy time in the Crystal Dome and earn a huge cash prize for Stand Up To Cancer. There's snow place like dome!
