Ashley Walters takes on the role of DI Luke Bascombe in the drama, and made quite an impression with viewers. Netflix fans may recognise him from also starring in Missing You, which was released earlier this year, but he's actually been in our lives for much longer than you may realise.

He added: "This revived a part of me that was dying a bit. It's taken a real friend of mine, Stephen, to see me outside of the box."
