Luther actor Warren Brown wants to see the hit drama turned into a film.
The 35-year-old, who rose to fame on Shameless and Hollyoaks, plays Justin Ripley in the BBC One crime drama.
He said: "There's always been talk of potentially doing a film.
"As early as the first series it was an idea. It's quite cinematic anyway. It may be in the rumour mill at the moment, but if it was to come to fruition it would be fantastic."
He said of his role as DS Justin Ripley: "I auditioned for it, and loved it from the moment I first read the script.
"You hope that everything you do is good, but every now and again you read a script and go 'wow, this is something a bit different', and then I got the call."
Warren said it was "fantastic" working with Idris Elba, who plays DCI John Luther, adding: "Not only is he a fantastic actor, he's become a really good mate now, so we have a great time at work and out of it. For me, I really love working with people that make you up your game."
The actor said of learning his craft as an actor: "Shameless was my very first thing, and Hollyoaks was almost like a drama school; six/seven months of being on camera every day. I learned so much and met some great people. I had a fantastic time."
:: Luther: Series 3 DVD, and Series 1-3 box set are available now.
