PARIS –Pascal Chaumeil’s romantic comedy “Heartbreaker,” Universal Pictures Intl.’s first French co-production, has scored the best opening week B.O. this year for a local film in Gaul.

“Heartbreaker’s” tally was goosed by a cut-price ticket offer, making B.O. gross — $9 million in normal circumstances — harder to estimate.

Starring Romain Duris and Vanessa Paradis, the pic was a major sales standout at January’s Paris Unifrance Rendez-Vous.

It bowed March 17 on 382 prints.

“Heartbreaker’s” real B.O. test will come with the Wednesday bow of Geraldine Nakache’s critically lauded comedy “Tout ce qui brille” and Fabrice Luchini starrer “My Father’s Guests” along with “Alice.”

Repped by Gregoire Melin’s Paris-based sales outfit Kinology, “Heartbreaker” will open L.A.’s City of Light, City of Angels fest and screen at Tribeca.

The film sold in all major territories except the U.S. and Japan.
