The comments I received about my post on casting got me thinking about locations for films and television series.
The 1983 film Lords of Discipline must be the classic location foul up, because as the actors with watered armpits tried valiantly to pretend they were in South Carolina it became obvious that at any moment a number 285 London omnibus was likely to go past the gates of the "Citadel".
The Kneller Hall School of Music in Twickenham doubled for the military academy with a few library shots of Charleston badly cut in to try and fool the audience as to the location.
The film was originally intended to be filmed on location at the Citadel in Charleston, South Carolina. It was shifted to production in England following the veto of the Citadel leaders, who had been warned about the time consuming delays of film production from the commandant of Valley Forge Military Academy, the scene for the 1981 military school film Taps (1981). The school and its alumni also believed that the novel was derogatory to the school (the story was set in Charleston at a "fictional" military college that was obviously based on The Citadel) and that the movie would do the same.
