Alicia Vikander and Tommy Lee Jones are also on board for the project, and Julia Stiles is set to return as well.
Paul Greengrass is back to direct and co-pen the script with Christopher Rouse. Frank Marshall again produces the action-thriller alongside Jeffrey Weiner for Captivate Entertainment. Greengrass, Damon, Greg Goodman and Ben Smith also produce. Rouse and Henry Morrison serve as executive producers.
Plot details are unknown at this time, though sources say Cassel will play an assassin tracking Bourne. Cassel joins the ranks of Clive Owen, Karl Urban and Edgar Ramirez, who played the villains in previous “Bourne” chapters.
Production is expected to begin later this summer. The film will bow on July 29, 2016.
Damon’s three Bourne movies, which began in 2002 and ended in 2007, grossed nearly $1 billion at the worldwide box office.
Cassel is repped by CAA and Agence Adequat and was most recently seen in “Child 44.” He can next be seen in “Partisan,” which is scheduled for release in the U.S. on October 2. Upcoming pics include “Tale of Tales” and “Mon Roi,” both of which premiered at the 2015 Cannes Film Festival, and he has completed lensing on “A Movie Life,” “The Great Mystical Circus,” as well as “It’s Only the End of the World.”
