Hinterland's Richard Harrington in Menai Strait charity swim
He is best known as DCI Tom Mathias in the Hinterland detective drama.
But actor Richard Harrington cut a rather different figure when he donned a red swimming cap and a wet-suit for a charity swim.
He joined 12 others on Sunday for the approximately one-mile swim across the Menai Strait to help raise money charity Awyr Las.
It was part of an attempt to raise £20,000 for the Alaw Unit in Ysbyty Gwynedd.
He said: "Everyone that took part did a super job."
The swim was held in honour of Irfon Williams, who is being treated at the hospital for bowel cancer. His wife Becky met the Welsh star and asked if he would take part.
Swim organiser Dewi Morris, 46, from Llanfairpwll, said: "We were delighted that Richard joined in.
"None of us could have done it without the 300-strong crowd cheering us on from the pier and the help of Duncan and his team from local company Seawake who provided support boats and assistance.
"We were all gutted that Irfon couldn't be there on the day because he was undergoing surgery on his liver. It was great that Becky and the kids could be there to be part of this special day."
The swim and a subsequent auction has raised more than £4,000.
