Essex and Wales collide when Gavin and Stacey fall in love, taking their friends, family and luggage with them. With the exception of scenes filmed on location in London in the first episode, the entire series was filmed in Wales, including scenes set in Essex. The house that was used as the Shipmans’ House (Gavin’s family) is in Dinas Powys, a village 1 mile northwest of Barry, where the Wests (Stacey’s family) live. In Series 3, both Bryn and Gavin’s cars have completely different registration numbers to the 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 (Cardiff registered in 2002) to HV54 (Portsmouth registered in 2004). Obviously, they are different cars. Featured in Gavin & Stacey: Outtakes (2007).

Gavin & Stacey is one of the best comedies I’ve seen in years. It has a wonderful cast and a brilliantly written script by Ruth Jones and James Corden. The series revolves around Gavin (a boy from Essex) and Stacey (a receptionist from Barry Island) who start their relationship over the phone while they’re at work. The feedback from the series has been so good that a second series has already been ordered.
