Hole in the Wall was a game show that aired on BBC One in the United Kingdom. This game was an adaptation of the Japanese game Brain Wall (also known as "Human Tetris") in which players must contort themselves to fit through cutout holes of varying shapes in a large polystyrene wall moving towards them as they stand in front of a swimming pool. Each week, two teams of television personalities competed for £10,000 in prize money to be donated to their chosen charity.
