Haut et Court is partnering with French sales company Wild Bunch on Emmanuelle Bercot’s (pictured) “150 Milligrams” (La Fille de Brest), a daring medical thriller a la Erin Brockovich, based on the true story of Dr. Irene Frachon, who uncovered one of France’s biggest medical scandals.

Pic marks Bercot’s follow-up to Cannes opener “Standing Tall.”

Carole Scotta and Caroline Benjo’s Haut et Court (“The Class,” “The Returned”) is producing “150 Milligrams.” Wild Bunch has acquired international sales rights.

Based on Frachon’s book “Mediator 150mg, How Many Deaths,” the movie is being written by Severine Bosschem (“Xanadu”) and Bercot.

“Borgen” actress Sidse Babett Knudsen has been cast to play Frachon, a lung doctor from a small town in Brittany uncovered the deathly damage caused by the diabetic drug Mediator. While her battle is still ongoing, Frachon has been hailed as a hero.

Benoit Magimel (“Standing Tall”) will also star.

“Sidse Babett Knudsen is the perfect actress to play this modern-day hero, she’s truly charismatic, relatable. Her unfamiliar face will allow us to create a fictional character based on Irene Frachon,” said Scotta, who also noted that Bercot has proven with past films her eye for talent.

“150 Milligrams” is a long-gestating project that Bercot, who is also an actress and won this year’s Cannes nod for her performance in Maiween’s “Mon Roi, has been developing since 2011.

Haut et Court has assembled a strong tech crew including Bercot’s regular collaborators: cinematographer Guillaume Schiffman (“The Artist”), set designer Eric Barboza and editor Julien Leloup.

Pic will start shooting in Brittany on Nov. 24. It’s been pre-bought by Canal Plus and pubcaster France 2.
