Creator Neil Cross told Variety he and Elba decided there was a great deal of “unfinished business” for the character to tackle in a new batch of episodes:
“Because we love John and wonder what he’s up to. 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.”
Luther first premiered in 2010. The series has received seven Emmy nominations to date. The most recent fourth season aired in December 2015. Stay tuned..
