Elsa Keslassy International Correspondent Pulsar Content has acquired “Niki,” a film about the famous French-American artist Niki de Saint-Phalle, for international sales. The Paris-based banner will introduce the period project to buyers at the Cannes market with exclusive first stills. “Niki” marks the feature debut of popular French actor Céline Sallette and stars Charlotte Le Bon (“The Walk” “Saint-Laurent”) as de Saint-Phalle. Le Bon recently made her feature debut with “Falcon Lake” — which bowed at Cannes last year — and previously starred in Robert Zemeckis’s “The Walk,” as well as Terry George’s “The Promise” and Jalil Lespert’s “Saint-Laurent.” Le Bon stars in “Niki” opposite Damien Bonnard (“Les Misérables“).
