Behind the scenes
Barking can be used as a shortened name of the borough, Barking and Dagenham, and as the name of the town of Barking which is located within that borough. Revenge of the Slitheen makes reference to the borough, rather than the town, but due to being at the edge of Mr Smith's map, "and Dagenham" is cut off.
