Following Season-Over-Season Growth, the Third Installment of the Belfast Police Drama will Debut on BritBox in Canada this May.

Richard Dormer, who played Gerry Cliff in the BAFTA and RTS award-winning Blue Lights, is returning for the fourth season of the Belfast police drama. Heralded as “One of the best cop shows on TV” (Eric Deggans, NPR) and “...Belfast’s answer to The Wire...” (Los Angeles Times), the 6 x 60’ series will also see the return of Hannah McClean as solicitor Jen Robinson and Jonathan Harden as disgraced former Inspector Jonty, in an episode that will answer serious questions from the past. 

Three years into their jobs as response officers, Constables Grace Ellis, Tommy Foster, and Annie Conlon are operating at their limit, facing a new threat on the streets that the police can barely control. Meanwhile the murder trial of Gerry Cliff exposes a dangerous and long-buried secret that leads to chaos both inside the police, and across the criminal underworld. As they grapple with big decisions about their future, Grace, Tommy and Annie must find the courage to face the greatest threat they have ever encountered: the truth.

Produced by Two Cities Television and co-produced by Gallagher Films for BBC iPlayer and BBC One, the multi-award winning show stars Siân Brooke (Sherlock, Trying) as Grace, Martin McCann (Trespasses, Hostage) as Stevie, Katherine Devlin (The Day of the Jackal, Vikings) as Annie, Nathan Braniff (Blue Lights S1-4) as Tommy, Joanne Crawford (Outlander: Blood of My Blood) as Helen McNally, Andi Osho (The Sandman, I May Destroy You) as Sandra, Frank Blake (Say Nothing, Normal People) as Shane, Abigail McGibbon (Ballywalter) as Tina, Dearbháile McKinney (Blue Lights S1-4) as Aisling and Andrea Irvine (Call The Midwife) as Nicola. The cast also sees the return of Cathy Tyson (Dune: Prophecy, Black Ops) who plays private members club owner Dana Morgan and Michael Smiley (Bad Sisters, Censor) as C3 intelligence officer Paul ‘Colly’ Collins.

We can’t wait to start filming it!” 

Stephen Wright, Two Cities Television and Louise Gallagher, Gallagher Films: “We are delighted to get the cast and crew back together for series four and welcome some new faces to the Blue Lights team. The appreciation for the show means so much to everyone involved and illustrates the power of fantastic teamwork.”

The 6 x 60’ series, written and executive produced by Declan Lawn and Adam Patterson, co-created and produced by Stephen Wright, Two Cities Television, and co-created and co-produced by Louise Gallagher, Gallagher Films, with support from Northern Ireland Screen.
