Screen time was divided up equally between the couples over the course of an episode, though occasionally some scenes would run longer; in Series 4, Episode 3, the scenes of Karen clubbing went on for ten uninterrupted minutes. These scenes were also a rarity for location filming; usually filming in public places was done on a Sunday during closing hours but the clubbing scenes in this episode were filmed during opening hours at the Music Box in Manchester. A hand-held camera was used to enhance the frenetic pace.
