We like to think them as perennial teenagers that’ll never grow up, but South Park creators Trey Parker and Matt Stone really have been over the past couple of years – and they’re set to establish themselves further by setting up their own production company.

A statement from the pair, reported by Entertainment Weekly, said “Having worked with several different studios over the years, we came to realize that our favorite people in the world are ourselves. We hope to work with ourselves for a long time and are excited to now work with ourselves in a much greater capacity.” The studios will be named Important Studios, with the pair rumored to be getting going on a film release of their successful TV show Book Of Mormon. That program has surprised many, essentially working as a South Park that’s suitable for everyone – the pair writing it alongside the still ongoing South Park itself, which has become one of the defining animation comedies of the past 20 years.

The studios will bring all of the pair’s projects together, including films Team America and BASEketaball. Formed in partnership with the Raine Group, the company is believed to be worth some $300 million, largely thanks to the assets of their long running foul-mouthed comedy.
