Larry Lamb has said he "would love" if rumours of a Gavin & Stacey film adaptation turned out to be true and admits the hit show has "become a real part of my life".
The 72-year-old actor, who plays Mick Shipman in the popular sitcom, said as soon as the Christmas special was over fans were asking for more.
The series returned for a one-off episode on Christmas Day last year, ending with a major cliffhanger for Smithy and Nessa, played by show creators James Corden and Ruth Jones.
Addressing whether there might now be a film, Lamb told Loose Women: "I remember talking to James, just to drop a huge name, about the whole thing of having had 10 years of being asked is there going to be any more Gavin & Stacey.
"So, you do the Christmas special, and then all that happens is you're back answering that same question - Is there going to be any more Gavin & Stacey?
"It's kind of like a drug that the nation is completely hooked on. I don't know if there is, I would love it if there is, it's become a real part of my life, and if there is it means I can say 'yes' instead of 'I don't know', because I don't know."
Asked if he is surprised at Corden's success in the US, where he hosts The Late Late Show with James Corden, Lamb said: "Not really., James is a phenomenon, he's been doing it for years and it's timing, in this game it's all about timing and the talent has always been there.
"After knocking around for years, since he was a young lad, it's something he and Ruth generated themselves but turned into this phenomenon, and then what he did was, because he's a very canny fella, he took what he already had and moved along with it, he's a very canny boy."
