Aisling Bea (Come Fly With Me), Amanda Lawrence (Above Suspicion), Edward Hogg (Misfits, Silent Witness), Tom Goodman-Hill (Ideal), Ricky Champ (Him & Her), Lizzie Roper (This Is Jinsy), Emma Pierson (Hotel Babylon), Barnaby Kay (Public Enemies), Bryony Hannah and Geoff McGivern have all been cast in the series. They join Jennifer Saunders and Sharon Horgan in the comedy project from Horgan and Holly Walsh.
The comedy series revolves around Helen Stephens (Sharon Horgan) who is falsely imprisoned for murdering her boss and sent to HMP Broadmarsh to serve her sentence. Initially, she is sure that it is only a matter of time before this horrible mistake is sorted and she is back to her old life. However, everyone else around Helen seems to be conspiring to keep her on the inside for one reason or another.
Jennifer Saunders stars as Margaret, the governor of Broadmarsh Prison, who believes that appeals are an irritation and a waste of valuable resources.
Geoff McGivern has been cast as Tony, Helen’s hapless lawyer, a specialist in “injury at work” claims, who thinks shouting “You can’t handle the truth” amounts to a convincing defence.
Bryony Hannah will play Christine, Helen’s arsonist cellmate who just wants a hug.
Aisling Bea has been cast as Laura, Helen’s self-obsessed younger sister, who is quite happy Helen’s inside as she’s moved into her flat and taken her job.
Amanda Lawrence will play Mary, Helen’s nemesis from her former work place, the head office of Entirely Tiles.
Edward Hogg has been cast in the role of Henry; the weirdo from work who is more than a little obsessed with Helen and realises that his weekly prison visits are the only guaranteed way to spend time with her.
Tom Goodman-Hill stars as Tim and Ricky Champ as Frank, prison guards and Margaret’s henchmen.
Lizzie Roper will play ‘Top Dog’, the boss among the Broadmarsh prisoners.
Emma Pierson has been cast as Mrs Bridges; the glamorous and not so grieving widow of Helen’s murdered boss.
Barnaby Kay has also been cast in the series, he will play Justin; Helen’s absent fiancé, who despite being her alibi, prefers Helen being in prison because he just can’t face dumping her.
