Gavin, Stacey, Smithy, and Nessa are now household names, but many other characters have helped propel the show to its legendary status. Their story is now told in The Gavin & Stacey Experience

In this BBC iPlayer programme ahead of the much-anticipated Christmas finale, Steffan Powell interviews actors and actresses who played some of these memorable characters to explore what it was like to be part of the show.

There are exclusive interviews with William Thomas, who played Father Chris, the vicar famous for the sandwich church scene; Gwynfor Roberts, who played Dic Powell, Barry’s Welsh speaking wheeler dealer who sells stolen meats; Catrin-Mai Huw, who played Natalie Lewis, the pharmacist and Stacey’s nemesis (who can forget the 32-second stare off?).

Plus Steven Meo who plays Owain Hughes, Gavin’s colleague who cracks the “before you ask, no I don’t” joke, and Gillian Elisa, who had two memorable cameos – the lady who sells lingerie to Nessa at a wedding fair, and a Welsh language campaigner who shouts at Bryn in a caravan park.

The Gavin & Stacey Experience is on BBC iPlayer from 13 December.
