Production has begun on The Split series 3 — there will be no series 4

The series, set in the fast-paced, complex world of London’s high-end divorce circuit is created by Bafta and Emmy Award-winning writer Abi Morgan (River, Suffragette, The Hour) and Executive Produced by Jane Featherstone (Chernobyl, Giri-Haji, Utopia), Lucy Dyke (The Split, Black Mirror, Ripper Street) and Lucy Richer (Small Axe, The Salisbury Poisonings, The A Word). The cast includes: the returning three Defoe sisters (Nicola Walker, Annabel Scholey and Fiona Button), their formidable mother Ruth (Deborah Findlay) and Hannah’s husband Nathan (Stephen Mangan).

The BBC has also revealed the return of Christie, played by Barry Atsma; the catalyst to the breakdown of Hannah and Nathan’s marriage in series two. Also returning to The Split series 3 are: Damien Molony (Tyler), Chukwudi Iwuji (Zander), Rudi Dharmalingham (James), Elizabeth Roberts (Liv Stern), Ian McElhinney (Prof Ronnie), Anna Chancellor (Melanie Aickman) and Kobna Holdbrook-Smith (Glen Peters), reprising his role as the Vicar who married Rose and James in season one.

Joining this formidable group is Lara Pulver (Sherlock) playing Kate, a leading child psychologist whose arrival adds a whole new layer of complexity to Morgan’s multi-layered examination of divorce and modern marriage. This farewell series, equal parts electrifying, witty and heartbreaking, continues to put the Defoe sisters and their matriarch at its heart; a group of powerful women working together to help their clients, their colleagues and each other as they continue to navigate the messiness of life.

You can read a lot more in the BBC’s announcement. There are no details as to when the show might air — our best guess would be early 2022. We’ll keep you posted.
