Endeavour is a British television detective drama series. It is a prequel to the long-running Inspector Morse and, like that series, is set primarily in Oxford. Shaun Evans portrays a young Endeavour Morse beginning his career as a Detective Constable with the Oxford City Police CID. The series is produced for ITV by Mammoth Screen and Masterpiece co-production for ITV Studios. Following a pilot episode in 2012, the first series was broadcast in 2013, the second in 2014 and the third in January 2016. A fourth series was ordered by ITV, began filming in late spring 2016, and premiered on 8 January 2017.
ITV broadcast a television film in the UK on 2 January 2012; in the United States, PBS aired it on 1 July 2012. It starred Shaun Evans as the eponymous police detective in his early career.Abigail Thaw, daughter of original Morse actor John Thaw, played the part of Dorothea Frazil in a scene at the Oxford Mail newspaper.
ITV commissioned a first series of four new episodes, filmed during summer 2012, and aired them from 14 April to 5 May 2013.
It was announced on 5 June 2013 that due to the success of Series 1, including consistently high ratings, ITV had commissioned a second series of four episodes. Filming commenced in Oxford in September 2013. On 24 September 2014, ITV confirmed that a third series of Endeavour had been ordered.
Before that third season of Endeavour screened on ITV, Evans told the Oxford Mail: "It's not like we have a six-year contract, there's none of that. It's day by day, year by year. I think this one is really good. We'll know when it airs if there's an audience for it and if we feel there's another place to take these characters."
