Comedian Matt Lucas has revealed the US version of Little Britain has been put back because of the writers' strike.
Lucas and Walliams have made three series of Little Britain to date
"We're members of the Writers Guild of America so our show is on hold," Lucas told BBC Radio One's Newsbeat.
"We obviously didn't want to break the strike, so we're just waiting for them to reach an agreement," he continued.
Members of the Writers Guild of America (WGA) began their industrial action on 5 November in a bid to get more money from DVD and internet sales.
The six-part series, starring Lucas and his comedy partner David Walliams, was scheduled to begin shooting in the US this autumn.
The show, which will be broadcast next year on pay-TV network HBO, was "pretty much written," according to Lucas.
"But when you're in rehearsal you change things and write new sketches, and when you're on the set you change things," he added.
The US series' title has yet to be confirmed, continued the 33-year-old, but would probably feature Little Britain in some form.
"This is effectively series four," he told BBC Radio One. "But there's a kind of way into it if you've never seen the show before."
The show sees them play a variety of outlandish comic characters
"I can't tell you too much about the characters because I don't want to ruin it," he said.
"But we've worked really hard on it, we've been writing solidly for about eight months, and we're really excited about it."
Little Britain started out on radio six years ago before spawning a TV sketch programme and a touring stage show.
