Finally, we've got our first trailer for the Gavin and Stacey Christmas special.

The BBC TV show will return for a special episode on Christmas Day and will again merge the worlds of Billericay and Barry Island.

The show, which ran for 20 episodes, from May 2007 to January 2010, is written by James Cordon and Ruth Jones.

It follows nice guy Gavin, played by Mathew Horne, who lives in the fictional Limetree Avenue, in “Billericay” - which is actually in Dinas Powys, in Wales.
