Sean Bean - Mark Cobden
Sean plays Mark, who has never been to prison before, but is served a four-year sentence for accidentally killing a man. Sean is a huge star, and is perhaps best known for his roles as Boromir in Lord of the Rings, and as Ned Stark in Game of Thrones. He also has a reputation for playing characters who get killed off, so we hope it's not the case this time around!
Stephen Graham - Eric McNally
In the new series, Stephen plays the caring prison officer who tries to help Mark out. The actor is hugely prolific, and has previously starred in Line of Duty, Boardwalk Empire and Band of Brothers. He is also set to star in Peaky Blinders season six.
Siobhan Finneran - Marie-Louise
Siobhan plays the prison’s Catholic chaplain, Marie-Louise, in the new series. The actress is also best known for her roles in Downton Abbey, Happy Valley and The Other One.
James Nelson-Joyce - Johnno
James plays Mark's fellow inmate, Johnno. He has previously starred alongside Sean in World on Fire, with Stephen on The Virtues, and as Liam in Mount Pleasant.
