Kai Owen came into Radio Wales to chat to Mal Pope and Louise Elliott about his role in Torchwood
Actor Kai Owen is enjoying success in the role of Rhys in the BBC's Cardiff-based sci-fi series Torchwood.
He also a keen runner and is training to run no less than three half marathons over the next few months.
Kai describes his character Rhys as being a typical Welsh bloke who brings some much needed normality to the sci-fi drama.
He admits that the character of Rhys was originally only supposed to appear in the first few episodes.
However he says he's built up a great on screen chemistry with Eve Myles who plays his wife Gwen in the series and his character has gone from strength to strength.
Interviewed by Mal Pope and Louise Elliott on BBC Radio Wales, Kai admits he was originally sceptical about whether a spin off series would work.
He attributes the success of the series in its own right to the great group of writers who work on Torchwood including Russell T Davies.
When he's not busy with Torchwood Kai, who's from Llanrwst in north Wales, enjoys keeping fit.
He decided to combine his desire to try marathon running with raising money for CLIC Sargent, a children's cancer charity which has supported his cousin.
Kai is looking forward to completing the Bristol, Cardiff and Coventry half marathons in the next couple of months.
