After sitting out the fourth installment in the Bourne film franchise, Matt Damon is back in the role that made him a legitimate action star. The new clip reveals that Jason Bourne remembers everything, but as Julia Stiles' Nicky explains, he "doesn't know everything." The spy intrigue involves a data breach "worse than Snowden," but fans will be coming back for the action. Look for plenty of close-contact fighting and a car chase that lays waste to the streets of Las Vegas. The clip also reveals a stellar supporting cast: along with the return of Stiles, there's also Alicia Vikander, Tommy Lee Jones and Vincent Cassel. Jason Bourne hits theaters July 29th.
