The first season of The Light in the Hall featured an almost entirely different cast, with the exception of actress Sian Reese-Williams reprising her role as Caryl. The inaugural series centred on bereaved mother Sharon Roberts (Joanna Scanlan), who grappled with life following her daughter's murder.
Series two star Mark Lewis Jones has disclosed that it was actually his friendship with Scanlan that persuaded him to join the new instalment. "Joanna Scanlan is a friend," he told Radio Times. "There are lots of people I knew in it, but in particular Joanna Scanlan's a mate, and so I was supporting her in watching it, and I thought it was great. It was absolutely wonderful. I didn't know there was going to be a second series, I had no idea about that, so I was just watching it as a punter. So when it came along that they were doing another story from that world, it was great to think, 'Oh, yeah it's really ripe for it, isn't it?' It's a great backdrop. So I'm thrilled actually, to be part of the Golau family."
