Following Thorne: Sleepyhead (2010) and Thorne: Scaredycat (2010), Mark Billingham expressed a desire to film all ten Thorne novels. Likewise, David Morrissey confirmed in February 2011 that a second series had gone into production. However, in a newsletter issued to members of his mailing list in December 2012, Billingham stated that Morrissey's role in The Walking Dead (2010) had suspended plans for the Thorne series. To date, no further episodes of Thorne have been produced.
The Jack Shepherd playing Jim Thorne is Jack Shepherd (I), and not the Jack Shepherd (V) the link goes to.
