Gavin & Stacey: What Happened Next

Gavin & Stacey: What Happened Next is a British sitcom, written by James Corden and Ruth Jones, that follows the marriage of a couple who began as a long-distance relationship. Mathew Horne and Joanna Page play the title characters, while the writers co-star as Gavin and Stacey's friends, Smithy and Nessa. Other prominent cast members include Alison Steadman and Larry Lamb, who play Gavin's parents, Pam and Mick, and Melanie Walters and Rob Brydon, who portray Stacey's mother, Gwen, and her uncle, Bryn. The theme for the series is "Run" by Stephen Fretwell. The show was produced by Baby Cow Productions for BBC Wales. It was initially set to run for a one-off eight-part series, but BBC One ordered a further eight episodes due to its success.

Main

 * Neil "Smithy" Smith (James Corden) – Gavin's oldest and closest friend, who also lives in Billericay, Essex. Smithy often gets jealous of Gavin and Stacey’s relationship, and has a complicated relationship with Nessa, who he has a son with. He remains in Billericay and works as a builder, but visits Barry most weekends.
 * Vanessa Shanessa "Nessa" Jenkins (Ruth Jones) – Stacey's oldest and closest friend, who is also from Barry. Nessa has several celebrity connections, such as MP John Prescott. She now lives in the house next door to Gwen formerly occupied by Doris, who left the house to Nessa in her will.
