Shooting began today on the third season of hit ITV crime drama Broadchurch. This is the last go-round for David Tennant and Olivia Colman (hot off The Night Manager) as Detective Inspector Alec Hardy and Detective Sergeant Ellie Miller. The pair reunites in Season 3 to investigate a serious sexual assault. Just added to the cast are 2016 honorary BAFTA winner Lenny Henry (The Pirates! Band Of Misfits, The Syndicate) and Roy Hudd (Robot Overlords, Coronation Street).

Lenny HenryAs previously announced, there are significant new roles for Julie Hesmondhalgh (Happy Valley), Georgina Campbell (Murdered By My Boyfriend), Sarah Parish (Atlantis), Charlie Higson (The Fast Show) and Mark Bazeley (Home Fires).

Among the returning cast are Jodie Whittaker and Andrew Buchan as Beth and Mark Latimer. Also coming back are Arthur Darvill as Vicar Paul Coates; Carolyn Pickles as newspaper editor Maggie Radcliffe; Charlotte Beaumont as Mark and Beth’s daughter Chloe; and Adam Wilson as Ellie’s son Tom.

Says creator Chris Chibnall, “We have one last story to tell, featuring both familiar faces and new characters. I hope it’s a compelling and emotional farewell to a world and show that means so much to me.”

The third season explores the consequences of a sexual assault as the Broadchurch community again comes under the scrutiny of Hardy and Miller’s investigation. The final chapter looks at the emotional cost to all of those involved and the irreparable damage to friendships and relationships. The team behind the series spent a year doing research with Dorset-based organizations which specialize in dealing with victims of sexual assault, and police advisors who specialize in investigating crimes of sexual violence.

Season 1 of Broadchurch was a revelation in contemporary UK drama and managed to keep a nation rapt for the finale’s big reveal in 2013. The show was then adaptated as Gracepoint in the U.S. (also starring Tennant), but didn’t find the same favor. Season 2 of Broadchurch, which wrapped in February 2015, averaged 9M viewers in the UK.

The eight-part final season is co-produced for ITV by Kudos, Imaginary Friends and Sister Pictures. Chibnall exec produces for Imaginary Friends; Jane Featherstone for Sister Pictures.
