The creator of the series, Neil Cross, who is also the screenwriter, said “Now what? It’s a question Idris and I get asked a lot. What happened to John Luther after we last saw him striding unbowed through the streets of his city, his blood red London? It can’t be over, ca it? There’s so much we don’t know. In the end, we picked up the phone to some old friends and asked if they’d like to find out what happens next. It turns out, they would. So that’s what we’re going to do. We’re going to find out what happens next”.
Season 4 of Luther aired its fifth and final episode on 15 December 2015.
