Written by acclaimed Bafta winning writer Abi Morgan (The Hour, River, Suffragette, The Iron Lady), The Split is about a female family of lawyers and will portray “modern marriage and the legacy of divorce”.
Watch the trailer below.
Walker plays divorce lawyer Hannah in the six-part series about the Defoe family, who navigates “scandalous affairs, big-figure settlements and fraught relationship battles”. Mangan (Green Wing, Episodes) will play Hannah’s husband Nathan.
Meanwhile Syal (Goodness Gracious Me) will star as Goldie, a woman going through a bitter divorce with her multi-millionaire husband.
The drama will be female-led behind the camera, too. It has been produced and directed by Jane Featherstone and Jessica Hobbs, the Bafta winning team behind Broadchurch.
When the drama was announced, Walker said: “I’m delighted to be joining the Defoe family and walking in Hannah’s shoes as she picks her way through other people’s marriages and relationships, all the while questioning her own.”
