Inbetweeners mania never really caught on in America—MTV’s 2012 version was yanked after one season. But the British sitcom has exploded into an enormous big-screen success at the U.K. box-office. The sequel to the hit 2011 film scored more than $21 million over the weekend, crushing Transformers, Dawn of the Planet of the Apes, How to Train Your Dragon 2, X-Men, and Guardians of the Galaxy‘s openings to claim the United Kingdom’s biggest weekend debut of 2014 and biggest-ever opening day for a live-action comedy.

Based on the popular British sitcom about four crude and horny teenagers, the first Inbetweeners film was supposed to be the final chapter for the characters after three seasons on television. The gang of four—not totally unlike the Porky’s crew or American Pie fellas—headed to Malta for a holiday to blow off steam after graduation. But when the film grossed $71.2 million in the U.K. (compared to a measly $36,000 in the U.S.), a sequel became inevitable.

“It got to the stage where so many people said that they loved the first one, and wondered if we were doing another one,” co-writer and co-director Iain Morris told “I’d go, ‘No,’ they’d go, ‘Why not?’ and it became like an embarrassing question! We don’t have a good answer—we got on really well, we’ve not fallen out. We just said we wouldn’t, and it’s not like it was closing it off. In the end, it just seemed mental to stop doing it.”

Indeed, especially from its producers’ point of view. The first movie cost barely $5 million and grossed a total of $88 million around the globe. The sequel, which follows the boys to Australia, opened even bigger than the original, so it might more difficult to say no should money be thrown at Morris and his collaborator Damon Beesley (Flight of the Conchords).

No-go, they claim. They recently told British media outlet Metro that there was “zero percent chance” of another Inbetweeners movie. Which makes some sense, since at least one of the raunchy teenage characters is now being played by a married father of two in his mid-20s. “I was 18 when we started and now I’m married with kids,” James Buckley, who plays foul-mouthed Jay, told the Express. “Simon [Bird]’s married, Joe [Thomas] lives with his girlfriend in his posh flat.”

It will be interesting to see if The Inbetweeners sequel receives an American release after the humbling showing of the first film in the States. Currently, it does not have a release date, nor a distributor.
