To twist this thread a little more...
Funny you should mention the Boer War movie Breaker Morant, Alex...
I've been shooting a History Channel documentary (for Aust and NZ) about saving our historic buildings, and one of these was Redruth jail in Burra, South Australia.
It's relevance here? It was the setting for the court case in the Breaker Morant film. The doors of the prison were blown off in one scene. (They built false ones for the explosion)
For those who are interested in an account of the event the film was based on there are several sources online including
this one.
