Olivier Assayas, who directed Kristen Stewart’s “Personal Shopper” and “Clouds of Sils Maria,” has come on board to helm the Cuban spy thriller “Wasp Network” from his own script.

“Wasp Network” is based on Fernando Morais’ book “The Last Soldiers of the Cold War.” RT Features’ Rodrigo Teixeira will produce alongside CG Cinema’s Charles Gillibert. RT’s Lourenço Sant’Anna and Sophie Mas will executive produce.

“Wasp Network” centers on Cuban spies in American territory during the 1990s when anti-Castro groups based in Florida carried out military attacks on Cuba, and the Cuban government struck back with the Wasp Network to infiltrate those organizations.

Assayas most recently wrote and directed “Personal Shopper,” which world premiered at last year’s Cannes Film Festival, where Assayas was awarded best director. IFC Films released the film in the U.S. on March 10.

Assays also wrote and directed “Clouds of Sils Maria,” starring Stewart and Juliette Binoche. The film had its world premiere at the 2014 Cannes Film Festival. Stewart earned France’s César Award for best supporting actress for her role in the movie — making her the first American actress to earn the honor.

Assayas was also nominated for the Palme d’Or for “Demonlover” in 2002 and for “Les Destinées” in 2000. He received an Emmy nomination in 2011 for outstanding directing for a miniseries, movie, or dramatic special for “Carlos” starring Edgar Ramírez, still regarded by many as his finest work and the nearest in its subject – terrorist Carlos the Jackal – to “Wasp Network.”

RT Features debuted two films at the Sundance Film Festival in January — Luca Guadagnino’s “Call Me by Your Name,” starring Armie Hammer, which was acquired by Sony Pictures Classics; and Geremy Jasper’s “Patti Cake$,” which was nabbed by Fox Searchlight. The company’s “The Witch” won an Independent Spirit Award for best first feature for Robert Egger. RT also produced James Schamus’ “Indignation,” Ira Sachs’ “Little Men” and Noah Baumbach’s “Frances Ha.”

Gillibert is a frequent collaborator to Assayas, having produced “Personal Shopper,” “Clouds of Sils Maria,” and “Summer Hours.” CG Cinema is in post-production on Deniz Gamze Ergüven’s “Kings,” starring Halle Berry and Daniel Craig.

Assayas is represented by WME and Intertalent while RT Features is represented by CAA.
