Gavin and Stacey follows the lives of a young couple from Billericay
Gavin and Stacey star Joanna Page has described the Christmas special of the comedy show as "heart-warming'.
The actress was talking at a photo call for panto stars, held in London, where she was promoting her London rendition of Cinderella.
She told Newsbeat: "It's very Christmassy and it's all revolved around the family. It's very, very funny.
"There's some lines in it that I just thought, 'Oh my God, that's what my dad said last year. So true to life but really heart-warming as well."
Joanna Page, who plays Stacey, explained that creating the show had already exhausted her Christmas spirit.
"We filmed that about a month ago, so I feel I've already done Christmas," she said.
"We were all really excited about filming the Christmas dinner. We had the turkey, the gravy, the brussel sprouts. But after we'd been filming it for four hours, I was like, 'Oh, do I have to eat another sprout?'
"We all just stopped talking to each other and were staring at the plate just thinking, 'Oh please make this end'. So we've already done Christmas dinner."
There have been rumours that a third series of Gavin and Stacey is heading our way, but Joanna doesn't seem sure whether it's in the pipeline or not.
She said: "I've no idea whether there will be a series three because I know that James and Ruth are very busy.
"So I've absolutely no idea. I'll probably read it on some website somewhere and find out from that before I know if we're doing one."
