UFO (TV series)
The North American DVD release of the series usually follows the production order, with a few diversions; a website ufoseries.com for the show offers seven possibilities of viewing sequence. According to "The Complete Gerry Anderson", the episode "Exposed" was intended to be aired second, but it was produced fifth and appears as the fifth episode in the American DVD release. It was only when the entire series was repeated by BBC Two in 1996–1997 that the series was shown in chronological production order in the UK for the first time.
