We gained access to these extensive catacombs courtesy of Itasca Locations, a company that provides unusual venues to film-makers. (Check out their web site for an impressive roll call of locations with pictures.) Previous productions to make use of the Clerkenwell House of Detention include the recent Sherlock Holmes movie (representing the tunnels below Westminster), Spooks, the Secret Diary of a Call Girl and St Trinian’s 2.
