The Grand Knockout Tournament

The Grand Knockout Tournament (colloquially also known as It's a Royal Knockout) was a one-off charity event which was shown on British television on 19 June 1987. It followed the format of It's a Knockout (the British version of Jeux Sans Frontieres), a slapstick TV gameshow which was broadcast in the UK until 1982. The event was staged on the lakeside lawn of the Alton Towers stately home-cum-theme park. However, the event used its own specially created immersing set, meaning that the location was not very recognisable in the TV broadcast..gptfims.com
