Many of the most popular television programmes ever to have been appeared on British television have been made on location in Manchester. From the longest running and still the most popular soap opera of the lot in Coronation Street, to the biggest comedy drama ever in Cold Feet; from the popular Queer As Folk, Clocking Off and Cutting It series to the almost national events that became of each episode of Cracker and Prime Suspect - they were all filmed here. Comedies such as Phoenix Nights, The Royle Family and Early Doors couldn't have possibly been located anywhere other than Manchester. The amazing landscape and architecture, coupled with the warm Mancunian sense of humour makes TV programmes filmed in Manchester that little bit more special.
