Gabrielle Creevey & Eve Myles Go Toe to Toe in 'The Guest'

The Welsh Renaissance in the U.K. continues apace. Not every series funded by BBC Cymru and the Welsh Government is being made in dual languages (yet). Still, the number of Welsh writers and the presence of Welsh stars headlining regular BBC TV series have grown exponentially. Case in point, actor Eve Myles, who first rose to prominence in the Welsh soap Belonging and the Doctor Who spinoff Torchwood (set in Cardiff, allowing her to use her natural accent). The more her star climbed, the fewer Welsh roles she played. However, that has changed recently, first with the dual-language series Keeping Faith and now with The Guest.

The Guest is not a dual language series, although BBC Cymru helped fund it. Hailing from the ultra-successful Quay Street Productions studio, the series was conceived by Welsh writer Matthew Barry (Industry) and surrounds Myles with Welsh co-stars, including the series' other lead actor, Gabrielle Creevey. In fact, one might say Creevey, an up-and-coming Welsh star who broke out towards the end of the 2010s in the TV series In My Skin, resembles something of a young Eve Myles from two decades ago when she was a fresh-faced Cardiff cop being confronted by alien life and Captain Jack Harkness.

Actually, how much Creevey looks like Myles when done up properly might just be the point. Check out the trailer.

Here's the series synopsis:

The Guest is a fast-paced story that centres on the toxic and beguiling relationship between a successful business owner, Francesca, and her employee, Ria. Ria has never had the time or opportunity to think about what she might actually want from the world. So, when she starts cleaning for Fran, she’s intoxicated by this confident and self-assured woman who encourages her to take control of her life, and when Ria flourishes, an intense friendship is forged.

However, when Fran’s advice leads to a shocking event, the lives of these two very different women become intertwined by shared secrets and dangerous plots. What follows is a compelling and manipulative game of cat and mouse. But just who is playing who?

Myles (Torchwood) stars as Francesca, with Creevy (Black Doves) as Ria. The main cast also includes Sion Daniel Young (Lost Boys & Fairies) and Emun Elliott (The Gold). Supporting cast includes Bethan Mary-James (Death Valley), Julian Lewis Jones (House Of The Dragon), Joseph Ollman (Queenie), Clive Russell (The Witcher), and Catherine Ayers (The Way).

Written and created by Barry, all four episodes of The Guest are directed by Ashley Way (Who is Erin Carter?) and produced by Karen Lewis. Both Berry and Way executive produce alongside Davina Earl & Nicola Shindler for Quay Street Productions, with Rebecca Ferguson & Nick Andrews for the BBC. 

The Guest will debut on BBC One and BBC iPlayer on Monday, September 1, 2025. The series has yet to announce an American distributor, but my money's on either BritBox or Hulu.
