Another series of Gavin and Stacey could become a possibility but fans will need to persuade writers Ruth Jones and James Corden, says Larry Lamb.
Larry reprised his role as Mick Shipman in the Christmas Day one-off episode, with the sitcom returning for the special nearly 10 years after it last finished.
The 72-year-old former EastEnders star responded to a fan on Twitter who had asked him to “please convince” show creators Ruth Jones and James Corden to do another series.
With Corden included in the message, Lamb tweeted: “Just keep up the pressure!!”
Larry also revealed who pleased he was with the reaction to the special episode, tweeting: “Well just to say how happy we all are that the show was as well received as we all guessed it would be … and thrilled to bits even so !! LoL.”
The Gavin And Stacey special secured the highest overnight Christmas ratings in 12 years, with the episode watched by an average of 11.6 million viewers.
It was the biggest festive special since Christmas Day 2008.
The episode picked up 10 years after the previous instalment and revealed that Gavin and Stacey (Mathew Horne and Joanna Page) now have three children, while Smithy and Nessa (Corden and Jones) were successfully co-parenting their son, Neil.
Gavin and his parents, played by Alison Steadman and Larry, travelled to the town of Barry in Wales to be with Stacey and her family, including mother Gwen (Melanie Walters) and eccentric uncle Bryn (Rob Brydon).
It ended on a dramatic cliffhanger, with a marriage proposal between two major characters left unanswered.
Nessa got down on one knee and asked on-off lover Smithy to marry her, but before he could respond the end credits rolled leaving fans none the wiser as to how he answered.
Viewers have now called for a new series in a bid to find out what happens between the popular characters.
However, Jones has already said there are currently no plans to bring Gavin And Stacey back for a string of new episodes.
The show originally ran over three series, plus a Christmas special, from 2007 to 2010 on the BBC.
