Channel 4's new prison drama hits TV screens this week featuring a stellar cast.
Screw is told from prison officers' point of view, as it follows their lives working in the fictional Long Marsh prison.
The new six-part TV drama is said by Channel 4 to show "life in prison as never before seen on British television".
Derry Girls star Jamie-Lee O’Donnell and Nina Sosanya of His Dark Materials are amongst the cast list.
See the cast list below.
- Nina Sosanya as supervising officer, Leigh Henry

Nina Sosanya is known for her role as Annie in Love Actually.
More recently, she appeared as Elaine Parry in the BBC series His Dark Materials. She also starred as Jess in Killing Eve.
Talking about her role in Screw, she said: "It opened my eyes to an area I was completely ignorant about.
"Prison is not something I think about, which goes to the heart of the whole problem. If you don't have any connection with it, it's out of sight, out of mind, and that doesn't seem like a great way for society to treat anyone. I also really didn't understand that female officers worked in male prisons, so that was intriguing to me."
As head of the 'screws', Nina's character Leigh keeps the inmates in line but also has her own secrets which threaten her career.
- Jamie-Lee O’Donnell as trainee prison officer Rose Gill

Jamie-Lee O'Donnell is famous for her role as Michelle in Derry Girls. She is due to appear in two films released this year: Unwelcome and Redeeming Love.
Jamie-Lee spoke of how "lucky" she was to be able to do drama and comedy, saying: "Some of the scenes in Screw are a million miles from Michelle [Derry Girls], which I'm really happy about."
The 30-year-old actress also revealed how she had to put on a Northern English accent for the role.
"I tried my best!" She explained: "I really enjoy doing accents and although I was nervous, putting my heart and soul into it, thankfully people on set responded really well."
- Laura Checkley plays "no-nonsense" officer Jackie Stokes
Laura Checkley is best known for her work on BBC comedy In My skin. She has also appeared on TV series King Gary and 2019 film Military Wives.
- Stephen Wight plays prison officer Gary Campbell

Stephen Wight is a regular on British TV. Recently, he has appeared on Silent Witness and Manhunt.
He has also starred in Sherlock, New Tricks and Misfits.
Talking about his character, Stephen said: "Gary hasn't achieved everything in his life he wanted.
"He wanted to join the police force, and it’s a source of frustration for him that he didn’t make it.
"Someone like him is straight-talking in the sense that he is not politically correct in a lot of his views or in the way he expresses himself."
- Faraz Ayub stars as officer Ali Shah
Faraz Ayub played Deepak in Line of Duty and has starred in The Capture and Silent Witness.
He said: "Psychologically it was really helpful: how they deal with life in prison, the lack of social life and how prison becomes your life.
"You have to have empathy, even for people who've committed heinous acts.
"Some of the prison officers told us about working with murderers and rapists, but they still had to show a sense of humanity to these people.
"You have to treat everyone within that environment as a human being and not judge them."
- Ron Donachie as prison officer Don Carpenter
Ron Donachie is known for The Jungle Book, Titanic, Doctor Who and Game of Thrones.
On whether he felt like a father figure to the rest of the cast, he said: "I certainly felt a lot older! The cast are tremendously capable and dynamic, so I don't think they were looking for a surrogate dad.
"They tolerated my eccentricities and the fact that it took me longer to climb a flight of stairs. As for Don, he isn’t a father figure either – he’s a closed-off man, but he’s good to Rose and Ali."
- James Foster as Google
James Foster is a longstanding British TV actor, known for his roles in Shameless, Emmerdale, and Doctors.
Not much is known about his character in the new Channel 4 series.
Screw will air on Channel 4 and All 4 from Thursday, January 6 at 9pm.
