Essex and Wales collide when Gavin and Stacey fall in love, taking their friends, family and luggage with them. The entire series was filmed in Wales, with the exception of scenes filmed on location in London in the first episode. The house that the Essexs used as shippers (Gavin’s family) is located in Dinas Powys, a village 1 mile northwest of Barry, where the Wests (Stacey’s family) live. In series 3, Bryn and Gavin’s cars have completely different registration numbers than in previous series. Gavin’s blue Saxo has changed from T-reg (MY 1999) to X-reg (MY 2000). Bryn’s green Picasso has changed from CV02 (MY 2002, registered in Cardiff) to HV54 (MY 2004, registered in Portsmouth). They are clearly different cars. Gavin & amp; Stacey: Outtakes (2007). RunBy Stephen Fretwell Played by Stephen Fretwell. An absolutely brilliant comedy, the acting is top notch and the writing is incredible. This is truly one of the best comedy series I have seen in years. Following the relationship between Gavin (Matthew Horne: Teachers and Catherine Tate) and Stacey (Joanna Page) from their initial phone flirtation, to their wedding day and on into married life. The show is brilliantly written by James Corden and Ruth Jones who also star as Gavin and Stacey’s best friends, Smithy and Nessa. (The ones who completely steal the show in my opinion.) Those who have given this show a poor rating clearly have no sense of humour and cannot appreciate decent comedy!
