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.

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.
