Location
The outdoor scenes were actually shot about a mile away in Lambeth and not in Pimlico. A set was built on a large Second World War bombsite just south of the Lambeth Road at the junction of Hercules Road. This has now been built on by 1960s municipal flats; however, the buildings on the junction of Hercules Road and Lambeth Road can still be recognised from the film as can the railway bridge going over Lambeth Road, particularly from the scenes where food is thrown to the "Burgundians".
