The Fifth Episode. Originally, Chatsworth Television intended to make a British version of the French show Fort Boyard, but when it became clear that the fort would not be available at the time of the pilot show, Fort Boyard's creator Jacques Antoine was consulted about developing an alternative format that could be shot elsewhere. As a result, the show ended up using a concept similar to Fort Boyard, but was substantially different in presentation and style. It was filmed on a very large set, originally at H Stage in Shepperton Studios, but in later series at an adapted aircraft hangar named Aces High Studios, at North Weald Airfield in Essex. Channel 5 later bought the rights to Fort Boyard and made their own version, using the original set, running from 1998 to 2001.
