One of the UK's most recognisable media personalities, Russell Grant, will be waltzing into the fictional village of Cwmderi to make a special guest appearance on the BBC's longest-running TV soap Pobol y Cwm - and his lines will all be in Welsh.
The astrologer, who famously took part in the ninth series of the BBC's Strictly Come Dancing in 2011, will bring a touch of showbiz glitz and glamour to a very dramatic edition of the serial on Friday, November 10 on S4C.
Russell lives in Maentwrog in north Wales and is proud of his Welsh roots, and this special guest role sees him delighting villagers with a surprise celebrity appearance at a local fundraising dance competition. The event is the brainchild of long-running character Eileen (Sera Cracroft) who, with husband Jim (Alun ap Brinley), organises the evening to raise money for BBC Children in Need and in memory of young character Courtney - a big fan of Strictly Come Dancing - who died a year ago.
In true soap opera style, though, the evening doesn't quite go to plan, and a dramatic turn of events before the night is through is set to have a significant effect on some of the villagers' lives over the coming weeks and months.
Russell Grant says he was delighted to be invited to take part in the popular drama serial, and glad of the opportunity to use some of his Welsh skills.
"I loved every bit of it, and everyone was so lovely. I didn’t have that many lines - but because I took a two-year Wlpan course in Gellilydan, I've always been absolutely fine with the pronunciation.
"I've lived in Wales longer than I've lived anywhere else. I moved to Cardiff in 1969 and was in pantomime at the New Theatre, with Ivor Emmanuel. Then I moved to Barry, where I was for quite a while, from there I moved to Abergavenny, and then I came up north in 1999. And I've lived in Snowdonia since then."
Russell partnered with Flavia Cacace on Strictly Come Dancing and his performances included famously taking the role of a human cannonball. As guest judge in the dance competition in Pobol y Cwm, he says he was suitably impressed by the standard of the dancing by members of the cast.
Russell also said:
"It was hilarious! And it's the most wonderful, wonderful storyline - watch out for Anita - Nia Caron - with the ostrich feather in her hair, and the lovely Colin - Jonathan Nefydd - who has everybody in hysterics, coming in looking like queen bee!"
Sera Cracroft said:
"Russell is a lovely man and he's just the same as you see him on screen, so full of life. He was very keen to put in a good performance, which was good to see from someone who's done so much television over the years. It was lovely to chat with him between takes - and great that he's able to speak so much Welsh!"
