He says the "sky is the limit" for his ruthless character and the 47-year-old is already excited about what is in store. He told Digital Spy: "I've maintained I'd like to see it come to a film, and that is where I think we are heading towards. And I'm looking forward to making that happen. It is happening.

“Obviously you can sort of be a little bit bolder with the storylines, maybe international, a little bit more up the scale, but John Luther is always going to be John Luther.” Cramming so much into less than two hours won't be a problem, it appears. He added: "We've made varied seasons, one season was six episodes, one was four - Luther's adaptable.

"I think if we can figure out the formula to keep an audience captivated for an hour and a half, on a movie, I think it has definitely got the attributes to make that happen. "When you scale a movie up, you have to give it size - that means taking it into other territories, internationally.
