The filming in Cambridge was carried out in Queens' College. This is where Stephen Fry attended in the 1970's and in 2005 was awarded an honorary Fellowship - allowing him to walk on the grass.
Market Shipborough, the fictional town in Kingdom, is actually Swaffham, where Stephen Fry lives in Norfolk.
Scenes in the first season which featured Stephen Fry driving Peter Kingdom's Alvis TE 21 were jeopardised when Fry was caught speeding in May 2006. His counsel successfully had the hearing to be postponed until the following December, allowing filming to resume unaffected (Fry was eventually banned from driving for six months).
Hermione Norris who plays Beatrice Kingdom, is married in real life to series creator Simon Wheeler.
