New MASTERPIECE Mystery Series Winter: Cast and Filming News
Additional Cast Join Stars Richard Armitage and Annabel Scholey
[February 2, 2026] MASTERPIECE PBS’ six-part police procedural, Winter has commenced filming in Bristol and Belgium with further casting announced.
The series features an unconventional forensic pathologist, Dr. Ethan Winter, played by Richard Armitage (Missing You, Red Eye, Fool Me Once), whose brilliance, sharp intellect and rule-breaking approach help the police solve some of the most complex murder cases.
Winter possesses an extraordinary analytical mind, capable of impeccable deductive reasoning which perfectly complements DI Lauren Bell, played by Annabel Scholey (The Sixth Commandment, Rivals, The Split), a meticulous, no-nonsense detective who is as driven as Winter when working on a case. Together they make a formidable team, as Winter’s genius and insight into the victims is invaluable to Bell and her murder squad detectives.
Further casting alongside Armitage and Scholey includes Jamie Kenna (House of the Dragon, Brassic), Carlotta Banat (Heads of State, 3 Body Problem), Josh Barrow (Hostage, Vera, Dear England), Adwoa Akoto (The Sandman, Surface), Jay Taylor (Manhunt, Ten Percent, Broken Bird), Rishi Rian (Ridley, Damaged), Deirdre Mullins (Bad Sisters, The Couple Next Door), Ellis Elijah (Mammoth) and Evie Coles (The Lady Grace Mysteries).
Each Winter episode features its own compelling, self-contained crime story, with resulting guest casting. A personal story thread, the unsolved murder of someone close to Winter, runs beneath entire season, as it still haunts his every move and he is intent on unofficially investigating the case and bringing the murderer to justice.
Winter is based on the television series Balthazar, created by Clothilde Jamin and Clélia Constantine and produced by Beaubourg Stories. The series is adapted by David Allison (The Couple Next Door) and Mark Greig (Ashes to Ashes).
Winter will be directed by Dries Vos (The Couple Next Door, Professor T) and Kaat Beels (Professor T, The Twelve) with Matt Baker (Professor T) producing the series. Jo McGrath and Walter Iuzzolino will executive produce the series on behalf of Eagle Eye Drama, part of ITV Studios.
Winter is an Eagle Eye Drama production co-produced with MASTERPIECE and in association with ITV Studios and Happy Duck Films. The series will be broadcast and streamed in the US by MASTERPIECE PBS.
Susanne Simpson is the Head of Scripted Content and Executive Producer of MASTERPIECE. MASTERPIECE is presented on PBS by GBH Boston.
