London on TV
This strange website lists TV episodes against their London locations.
This is Theatre
Theatres - Information on London theatres - historical, architectural - and about the shows.
"On this site there are over 1,900 pages of information and more than 4,700 archive images on the history of Music Hall and Theatre in the UK."
About film and maps: London, Paris and Geneva in particular. Difficult to describe but we lost ourselves in it for a long time.
