The Escapist is a great film by Rupert Wyatt (2008) about a bunch of desperados running away from a British prison.
Frank Perry and his inmates escape by oppressive underground tunnels. One of it is an abandoned tube station in Central London, Union Street. The station is the perfect stage for a moment of suspended reality in the film. It looks phantasmagorical and just as sad and hopeless as the drama of the film.
I have not found any information or picture about the station. It is not on the list at http://www.disused-stations.org.uk/. It might as well just be a fictional stage of the film.
