When Roy loses his jacket (and ID and money) and is thrown out of his building, he wanders the streets, mostly in and around Northcote Road, Battersea, London; but at one point as he asks a passerby for "50p for a phone call", the building behind him (13 Tottenham Street) indicates that scene was recorded in Fitzrovia, London, some 5 miles away from Battersea.
Katherine Parkinson (Jen) and Lucy Robinson (June) also appeared together on the TV show, "Doc Martin": The Holly Bears a Prickle (2007).
