The creator of the new four-part thriller has said it was “really important” to film and produce it in Cardiff.
Matthew Barry, a BAFTA Cymru-winning screenwriter based in London and Los Angeles, said he was “very pleased” to have centered the guest on the city where he was born.
He said it was also “really important” to show a more prosperous Cardiff side in the series.
One person who had already seen the first episode of the four-part series said that “it’s so good not to see the Gherkin anymore,” Barry added.
The show stars Welsh actors Eve Myles, Gabrielle Creevy, Sion Daniel Young and Emun Elliott.
“I was born and raised in Cardiff and I think what’s so great about our show is that we see a different side of Cardiff,” said Barry, who also executive produced the drama.
“We see a lot of affluence – a lot of wealth – and it’s not something you see a huge amount of on screen in Wales.”
Barry, who also wrote the one-off drama Men Up, said: “We also have a slightly darker side, and it’s the clash of these two worlds, which Eve described as like pulling the pin out of a grenade.”
Myles and Creevy play a successful business owner and her new “lucky” cleaner who lives on the breadline, Barry said.
He said their performances are “incredible, honest and real” as the two characters become friends before their relationship becomes increasingly toxic and similarly addictive.
“It’s a decent fun thrill ride, so I hope people enjoy it,” he said.
