By Jessica Raine and Clarke Peters have signed on to star in ITV series Jericho.
The eight-part drama, also featuring Hans Matheson, comes from Sherlock and Doctor Who writer Steve Thompson.
Set in the Yorkshire Dales in the 1870s, Jericho follows a community of pioneers, settlers and outcasts, many of whom have secrets to hide.
Raine plays Annie Quaintain, a woman who is left shattered and penniless by her husband's death. Turfed out of her home and shunned by her former friends, she leaves for Jericho with her two teenage children in a bid to rebuild their lives.
Peters is starring as railway agent Ralph Coates, who has a past that keeps him looking over his shoulder.
Ralph offers Annie a helping hand, leading Annie to open a boarding house for the navvy labourers in Jericho.
Mark Addy, Lorraine Ashbourne and Amy James-Kelly will also appear in the programme, which will go into production later this month in North Yorkshire.
