On the beach - the cast of Gavin & Stacey enjoy Barry Island in the sun
Ruth Jones admits it was 'very emotional' filming the third and final series of Gavin & Stacey which returned to our screens in November.
The setting for the award-winning BBC TV comedy moves back to Barry Island as Gavin starts a new job in south Wales.
The Bridgend-born comedian and writer, who also plays Nessa, says this will definitely be the final series.
"Where would we go with it? No, it's really time to say goodbye to these characters now," she says.
"But we've never ruled out the idea of a special maybe in a few years' time," she added.
Matthew Horne and Joanna Page are well loved in the title roles
As Gavin begins his new job, the move to Barry Island means big changes for the whole family.
His parents Pam and Mick have to adjust to an empty nest while Gwen's got a full house again.
Stacey is in her element, but will this finally be the solution to the couple's long-distance problem? And how will Gavin take to living in Wales?
Smithy questions their friendship along with his own role as father - and with Dave Coaches on the scene and now engaged to Nessa, will Smithy find himself pushed out of the frame?
How will life in a caravan work out for Nessa and her soon-to-be husband Dave?
Joining the cast as Smithy's mum, Cath, is Pam Ferris.
It marks a return to south Wales for the actress best known as Ma Larkin in The Darling Buds of May who was brought up in Aberkenfig near Bridgend.
Jones, who writes the series with co-star James Corden (Smithy) says a highlight of the final series was to showcase Barry Island in the sun.
"There'll be a whole episode set on the beach which was really fun to film," she says.
"Loads of people were there watching too, so it was a real party atmosphere," she added.
Jones and Corden may work together on a feature film
"And we were so lucky with the weather - later on in the shoot we had torrential rain, and the place where we were filming nearly flooded.
"So those beach days... the gods of Barry were smiling down on us then."
She admits there was a very sad feeling among the cast, knowing the show was coming to an end.
"In the final week me and Jo Page (Stacey) just couldn't stop crying. We were pathetic and we looked like frogs. And on the last day me and James were awash.
"It sounds silly I know, but it's been a big part of our lives for the past three years... but, y'know, things have to move on.
"As Nessa said in episode one of series one, 'times change - people move on.' And they do.
"I like to think that we dipped into the lives of Gavin and Stacey and their family and friends for a couple of years, and now it's time to dip out again and let them get on with it.
"I actually do believe sometimes that these people exist! Am I going mad?"
As for the future, Jones reveals that she and Corden are considering an idea for a feature film although it won't be based on their hit series.
"Both James and myself think Gavin & Stacey very much belongs to the little screen, not the big one," she says.
"And there's nothing wrong with that. It's just the right medium for it.
"So why spoil it by trying to turn it into something it's not? Now Gavin & Stacey the musical... that's a different story!"
The final series of Gavin & Stacey begins on BBC One on Thursday 26 November at 2100 GMT
