Gaynor Faye, who played Lauren Harris in all four series of the show, revealed on Channel 4 show Steph's Packed Lunch: "We're revisiting the characters and it's really exciting. Hopefully we're shooting it next year."
A source told the newspaper: "James and Ruth on screen again is the reunion everyone wants, albeit not Gavin & Stacey. The cast were all approached about filming a movie version - an early script has been written, and is ready to go.
"If it gets the green light, James will reprise his role as Jamie Rymer, while Ruth will play Kelly Chadwick again.
"The film would also be a huge tribute to Kay who helped change so many of the cast's lives. They all would love to do something to thank her for her brilliance. It's still early days but a very exciting project."
