A reunion involving Gavin, Stacey, Smithy, Nessa and Uncle Bryn has been caught on camera in Barry.

The Bafta-winning BBC sitcom Gavin and Stacey, about a long-distance relationship between a girl from south Wales and an Essex boy, was last screened in the UK in 2010.

In May, co-writer and star James Corden announced its return.

The cast filmed scenes over the weekend surrounded by Christmas decorations, watched by crowds of onlookers.
