Neil Cross has already written the screenplay that follows John Luther's early career as a detective, when he is still married to Zoe (Indira Varma). The final scene of the movie will be the first scene of the TV series, where John Luther returns to the Serious Crime Unit after serving a seven-month suspension.
Earlier this year, Idris Elba had this to say about the prospect of a Luther movie.
It isn't known if Neil Cross plans on directing this untitled movie or not. Neil Cross has already written a prequel novel entitled The Calling, which centers on the case involving a child killer that results in Luther's seven-month suspension.
