Essex and Wales collide when Gavin and Stacey fall in love, bringing their friends, family and luggage with them. Apart from the scenes filmed on location in London in the first episode, the entire series was filmed in Wales, including the scenes set in Essex. The house that was used as the Shipmans' (Gavin's family) home is located in Dinas Powys, a village 1 mile north-west of Barry, where the Wests (Stacey's family) live. In series 3, Bryn and Gavin's cars have completely different registration numbers from the previous series. Gavin's blue Saxo has changed from a T-reg (MY 1999) to an X-reg (MY 2000). Bryn's green Picasso has changed from a CV02 (MY 2002, registered in Cardiff) to an HV54 (MY 2004, registered in Portsmouth). They are clearly different cars. Featured in Gavin & Stacey's 1999 series, ... Stacey: Outtakes (2007). Starring Stephen Fretwell. I have to say I can't quite understand the previous reviewer as I think they're on a different planet to everyone else and I felt compelled to set the record straight. Gavin & Stacey is one of the best comedies I've seen in years. It features a wonderful cast and a brilliantly written script by Ruth Jones and James Cordon. The show revolves around Gavin (an Essex boy) and Stacey (a receptionist from Barry Island) who begin their relationship over the phone while they're at work. The feedback for the series has been so good that a second series has already been commissioned.
