Mexican romcom “Marry If You Can” (“Casese quien pueda”) is charming its way to box office bliss, having opened numero uno on Valentine’s Day to earn 45.5 million pesos ($3.4 million) on its first weekend, beating “Robocop” and “The Lego Movie,” and growing at a faster clip than all-time local blockbuster “We Are Nobles” at the box office.

Pic claims the second largest opening weekend for a domestic pic in Mexico after Eugenio Derbez’s “Instructions Not Included,” which grossed 61.3 million pesos ($11.4 million) in its first week and ended up with $46 million. In the U.S., “Instructions” was a hit in the U.S. for distrib Pantelion with $44 million.

Penned by its lead actress and co-producer Martha Higareda and helmed by Marco Polo Constandse, “Marry If You Can” tracks a young bride-to-be, played by Higareda, who finds out that her fiance has cheated on her while she’s being fitted for her wedding gown. Heartbroken, she gets drunk, falls into the back of a pickup truck and ends ups in the middle of a jungle. Still dressed as a bride, she struggles back home where her sister, played by Higareda’s real-life sister Miri Higareda, and best friend are looking for her.

The Higareda sisters’ production shingle NeverEnding Media produced pic along with Sin Sentido Films and Televisa affiliate, Videocine, which distributed pic.

Higareda, who has starred in such local hits as “Amar te duele” and “Ninas Mal,” crossed over to English-language pics in 2008 actioner “Street Kings” opposite Keanu Reeves and most recently in “McFarland,” Disney’s upcoming sports drama with Kevin Costner.

Repped by ICM and Untitled, Higareda is currently working in the skein “El Mariachi,” which Sony Pictures Television and Teleset are producing in Mexico for the Latin American market.

NeverEnding Media is prepping its next pics “Tierra Rojas” and “Fuga de Reinas.”
