Mark Williams has revealed he will be the "twisted fire starter" in his house this Christmas.
The Harry Potter star - whose new BBC detective drama Father Brown begins in the New Year - has been in Australia co-presenting the Doctor Who Symphonic Spectacular at the Sydney Opera House, and is feeling the chill this Christmas.
Mark revealed: "I used to be chef at Christmas, but I'm not so much now. I shall be fire builder, because we've got wood burning stoves and we'll get back from Australia and I know we're going to be freezing.
"And I've got a farmer who's a friend of mine, whose got a thing about Christmas logs, he says you've got to pick out the Christmas logs for Christmas day.
"So I shall be the fire starter. I shall be the twisted fire starter!"
Mark, who starred with Julie Walters, Rupert Grint, Domhnall Gleeson and Bonnie Wright as the Weasley family in the Harry Potter films, revealed he is planning a family reunion in the New Year.
He said: "We were talking about having a Weasley reunion. Now because there's hardly any filming done in London, it's pretty difficult travelling at the moment, but I think we'll try and organise a Weasley reunion."
