From Downton Abbey to Mr. Selfridge to Broadchurch, the UK’s ITV has been enjoying a successful run of original drama series. Looking to continue the trend, the network has just ordered a second four-part outing for Inspector Morse prequel Endeavour, starring Shaun Evans and Roger Allam. A feature-length first episode of the crime drama debuted on ITV in 2012 and was co-produced by Masterpiece in the U.S. The film was one of ITV’s highest performing dramas of the year. A first four-part series then aired in 2013 and consistently won its time slot for ITV, averaging 7M viewers and a 25% share. The new series will be a quartet of 120 minute films set in 1966. Evans plays a young Morse and Allam is Detective Inspector Fred Thursday. Russell Lewis writes the series and novelist Colin Dexter, who created Morse, is a consultant to producers Mammoth Screen. Lewis will also exec produce with Mammoth’s Michele Buck and Damien Timmer. Camille Gatin is producer with directors still to be named. Production stars in Oxford later this year.
