Idris Elba has promised a "high-octane" third series of Luther.

Luther creator Neil Cross recently revealed that he is planning to produce a film adaptation of the BBC crime drama, once the TV version has ended.

"We're going back to a four-episode format [for series three], high-octane Luther stuff," Elba confirmed to Vulture. "We're going to close out a couple of storylines."

The actor confirmed that he and Cross are "really preparing for the big screen", calling a Luther movie a "very strong goal".

"It's not in stone yet, but it's something we definitely want to aim towards," he said.

Elba added that much of the show's success is down to its "ridiculous" quality and the "American-esque" nature of his character John Luther.

"Luther - he's way bigger [in his reactions] than an English cop would ever be," he said. "I think part of the TV show's popularity in England is that it's sort of ridiculous to see an Englishman that big in a lot of these scenes. But it actually works because of how grandiose some of the crimes are."

Prometheus star Elba first announced his intention to make a Luther film in June 2011.

"I really do want to make Luther into a film," he said. "I think that's where the ultimate Luther story will unfold - the big silver screen."
