The Light in the Hall, also known as Y Golau, is a brand new drama coming to Channel 4 this January.
The series is filmed in both English and Welsh and follows the story of journalist Cat Donato, originally from the same town as Ela Roberts, who has always been obsessed by her murder.
For Cat, it was personal because Ela had been a part of her circle of friends, but prior to her murder, Ela had been ostracised over a silly teenage squabble - a fact that Cat has tried her best to forget.
The six-part series is written and created by Regina Moriarty (Murdered by my Boyfriend) and directed by Andy Newbery (Keeping Faith) and Chris Forster (Hidden). As well as starring Killing Eve's Alexandra Roach as one of the series leads, the small cast is also made up of other familiar faces.
Read on to find out more about the cast of The Light in the Hall.
The Light in the Hall main cast
Alexandra Roach plays Cat Donato
Who is Cat Donato? Cat is a journalist who, now older, is still fixated on the events around her teenage friend's murder. With the news of Joe’s parole hearing and the prospect of his release, it prompts Cat to investigate and write the true events surrounding Ela's murder.
What else has Alexandra Roach been in? The Welsh actress has been in a number of notable television series, including Sanditon as Diana Parker and No Offence as DS Joy Freers. She has also starred in Killing Eve, Inside No. 9 and Black Mirror.
Iwan Rheon plays Joe Pritchard
Who is Joe Pritchard? Joe is a quiet, unassuming gardener who was arrested for Ela’s murder after her DNA was found at his caravan. Joe confessed to killing Ela but wouldn’t, or couldn’t, say why or what he did with her body.
His parole hearing and potential release brings the two women at the centre of this drama much turmoil, as well as highlighting burning questions they still have about Ela's murder.
What else has Iwan Rheon been in? Rheon is best-known for his roles as Simon Bellamy in Misfits, Ramsay Bolton in Game of Thrones and in recent Sky original Christmas film A Christmas Number One, alongside Freida Pinto.
Joanna Scanlan plays Sharon Roberts
Who is Sharon Roberts? Ela's mother and someone who has never stopped grieving the loss of her daughter. Still disturbed by her memories of that last day, Sharon needs resolution. With Joe's release imminent, Sharon sees it as a chance to confront the man who killed her child.
What else has Joanna Scanlan been in? Scanlan has starred in many beloved TV roles over the years in series like The Thick of It, Getting On, No Offence, Dracula and The Larkins. She most recently won a BAFTA for her leading role in 2020 film After Love.
