Germany's Atlas International has picked up worldwide sales rights to Constantin Film's latest German box office hit, Ants In The Pants (Harte Jungs), directed by Marc Rothemund.

The comedy, about a teenage boy's sexual awakening, is being unveiled at the Cannes Film Festival where it will be screened with English subtitles.

"Some buyers were disappointed they couldn't see the film at the recent MIP-TV market," said Atlas president Dieter Menz. "But we believe Cannes, and a filled cinema, create the best ambience for selling a film."

Harte Jungs took $2.4m from 450 screens in its opening four days in Germany, making it the most successful opening by a domestic film in the last six months. The film had grossed $7.5m by April 24. After Cannes, the American Pie-style comedy will be dubbed into English.
