It’s been three long years – give or take – since sexy Idris Elba graced our TV screens as sexy DCI John Luther, and people have been waiting patiently to get another glimpse of him.

The thing is, Elba’s now a global superstar who absolutely everyone, my mum included, loves. He’s too busy being on Sky adverts and the like to film series for the BBC.

Until now, that is, because only a few days ago the BBC tweeted that Luther season 5 would be showing over the festive period and furthermore, we got a brief glimpse of the action in a short interrogation scene clip.

That was all well and good, of course, but now BBC have turned it up a notch and given us the whole thing – and when I say the whole thing, I of course mean a reasonably-lengthed trailer.

Have a watch…

Side note before we get into it; I really hate how all trailers now have a 1-2 second glimpse of action before the actual trailer kicks in. Seems unbelievably unnecessary.

So wow, Alice Morgan’s back! We all thought she was dead. I wonder how that ones going to play out and whether or not Luther will drop his morals once more to get off with a full-on murderer.

As always, it’s not a walk in the park for Luther, and this season will see him exploring the ‘deepest depths of human depravity’. Nice.

The synopsis reads:

While the monstrous and seemingly indiscriminate killings become ever more audacious and public, Luther and new recruit DS Catherine Halliday played by Wunmi Mosaku are confounded by a complex tangle of leads and misdirection that seems designed to protect an untouchable corruption.

But even as the case brings him closer than ever to the true face of evil, a reluctant Luther is forced to confront the unburied demons of his own recent past.

Striding back into the line of fire, he must choose who to protect and who to sacrifice.

Whatever his next move, it will have devastating consequences for those around him – and change John Luther forever.”

Seems like he has a habit of being changed forever.

Anyway, I can’t wait.
