John Simm will be joined by his ‘Life on Mars’ co-star Philip Glenister's brother Robert in ITV drama ‘Grace’.
Season four of ITV's Brighton-based detective drama - which is based on the best-selling novels from renowned author Peter James - is currently being filmed.
John, 52, is returning as Superintendent Roy Grace alongside Richie Campbell (DI Glenn Branson) and ‘Hustle’ star Robert, 63, is joining the cast, too, though his role is not known at this time.
John said: “I’m so pleased to be back on set, filming series four of Grace.
“Four of Peter James’ Roy Grace novels are being adapted for this series and Grace fans will be pleased to know the stories are as dark as ever with lots of twists and turns.”
ITV Drama Commissioner, Huw Kennair Jones, said: “We’re thrilled to be making another series of Grace.
“John and the team continue to bring Peter’s brilliant characters and stories to life in such an exciting way. It’s also great to be working with Tall Story and Vaudeville Productions again as we head back to Brighton for four brand new cases.”
Author Peter James added: “As a writer, the chance to have such a phenomenal and collaborative cast and crew to bring my novels to life continues to be a dream come true.
“Audiences have so generously embraced the series with such enthusiasm and I cannot wait for Roy Grace fans, old and new, to see these four new episodes.”
The first film in the series, 'Dead Man’s Time', follows: "A vicious robbery at a secluded Brighton home, draws Grace and Branson into a puzzling enquiry when thousands of pounds worth of beautiful antiques are stolen from the house. As Grace digs deeper into this mysterious crime, he unearths a web of ancient grudges - a web which leads him down a dark, murderous trail through the world of Brighton antiques, in a race against the clock, to untangle who is at the heart of this robbery, and bring Gavin Daly the answers he has been desperately chasing for many years."
