LONDON — Protagonist Pictures has taken on worldwide sales rights outside Nordic territories to “Klown Forever,” the sequel to the 2010 hit Danish comedy “Klown.” In addition, Protagonist has taken over worldwide distribution of the first film and will be talking up both at Cannes next week.

Based on the long-running TV series (2005-08), the Klown films center on the antics of two thirtysomething best friends and comedy partners, Frank, played by Frank Hvam, and Casper, played by Casper Christensen. Hvam and Christensen also wrote both features, while one of Denmark’s biggest filmmakers, Mikkel Norgard (“The Keeper of Lost Causes”), is the director and Jesper Zartov produces.

In “Klown Forever,” Frank and Casper’s friendship is tested when Casper decides to move to Los Angeles and pursue a solo career there. Determined to win back his friend, Frank follows him to California for a holiday of spectacular misadventures.

Among those making cameo appearances in the film are Isla Fisher, Maroon 5 frontman Adam Levine and Danish heartthrob Nikolaj Coster-Waldau (“Game of Thrones”).

“Klown,” which was acquired for U.S. remake by Warner Bros., has a host of self-declared celebrity fans including Sacha Baron Cohen, who hired Hvam and Christensen to write his next film, “The Lesbian,” at Paramount.

“Klown” was distributed by Nordisk in Scandinavia and grossed over $10 million in Denmark alone; it was sold by TrustNordisk to Drafthouse in the U.S. and Arrow in the U.K. among other territories.

Nordisk is releasing “Klown Forever” in September in Denmark; Hvam and Christensen will be in Cannes to launch the film to Danish and international media.

Hvam and Christensen’s production company Nutmeg Pictures produced the film.

“We are so proud to be a part of the ‘Klown’ universe with Frank, Casper, Mikkel and Jesper,” said Mike Goodridge, CEO of Protagonist. “The first ‘Klown’ is unquestionably the funniest film I have ever seen, and, like all the best comedies, combines side-splitting humor with a great big heart. The second film takes the friendship between our two heroes into newly complicated, dangerous, risqué, tender and funny directions, and we feel it will win over a whole new legion of fans around the world.”
