The series will be remade by NBC, the same channel behind the American version of The Office. Steve Coogan, the head of Baby Cow Productions which makes Gavin and Stacey, will oversee the production of the remake, alongside James Corden and Ruth Jones, the show’s creators (pictured).

Corden told The Times: “It’s really exciting. The idea is that Gavin will come from New Jersey, which has the same relation to New York as Essex does to London. Stacey will be from South Carolina. They meet in Times Square. I hope they keep the British names but they may have to change them.”

The second series of the British version is due to start on BBC Three on Sunday 16th March with a double-bill. Corden said that he expects the British version to finish with a Christmas special, whereas the American version will go on, similar to the current adaptation of The Office. The BBC has also asked Corden and Jones to make their own sketch show, as well as writing film scripts.
