Luther may not have been on our screens since 2015, but that doesn't mean that we haven't been eagerly awaiting updates on a fifth series.
Last year, we heard that filming for the new series would begin in early 2018, and now our favourite Idris Elba has shared some exciting behind the scenes footage while they begin filming. Take a look here...
Alongside the video, Idris wrote: "It's good to be back in London, back in the coat. #Luther BBCone."
It's good to have you back too, Idris.
It won't just be us who feel that way, as the actor received critical acclaim for the role and has also been awarded a Critics' Choice Television Award, Golden Globe Award, NAACP Image Award, and Screen Actors Guild Award for his role in the drama.
Fans were quick to share their excitement, with one commenting: "Glad it's coming back, but can it be a full length series this time please? A couple of episodes just isn't enough!"
Another added: "Long overdue, great series! Always exciting to see a new Idris project! Mind you I saw an episode of AbFab with a very young Idris playing a Gigolo - that was funny!"
Series creator and writer Neil Cross revealed back in December that production for the fifth series would begin this month.
"I [have] delivered the final episode of Luther series five," Cross explained, speaking to Deadline."We're in prep right now and we're doing a bit of casting and we start shooting in January.
"For some reason, I always seem to shoot in the depths of winter."
In the same interview Cross also discussed the prospect of a Luther film. Turns out Cross is totally up for it, and that he's game whenever Idris Elba's hectic schedule allows it.
"The fact is that Idris and I are bound in this shared relationship with this character and every TV series, we think it's going to be the end," he said.
"Not least because Idris is a very busy and has a successful career, but we always miss him when it's over and then I start coming up with ideas. We always come back for more, for no other reason than we love doing it.
"Hopefully in some incarnation, the character will continue."
He continued, saying that a film will always be at least slightly different from the TV series because of 'how long you have to tell a story'.
"Ultimately, whatever Luther story you tell, in whatever medium, has to focus on that character so in some ways it will be exactly the same because it will be about him," said Cross.
Fingers crossed, eh?
