International stars and some familiar faces make up the Treadstone cast, the Jason Bourne spinoff series on USA Network. Executive produced by Tim Kring (Heroes) along with Ben Smith and Jeffrey Weiner of the Bourne film franchise, Treadstone expands the Bourne universe and introduces new assassins into today's geopolitical setting. The new series, like the Bourne movies, is based on the original novels written by Robert Ludlum.

Set in the present day, years after the rogue agent played by Matt Damon was last seen in 2016's Jason Bourne, Treadstone reveals the origin of the secret CIA program that created Bourne and numerous other sleeper agents-turned-assassins like him. The other Treadstone agents (aka Assets), who have been dormant and inserted into society all over the world, are mysteriously reawakened and sent on new missions. Meanwhile, agents within the CIA attempt to solve the mystery of how Treadstone, which was officially deactivated during the original Bourne film trilogy, is back in play, what the Assets' overall mission is, and who is secretly pulling the strings.

Treadstone was announced in April 2018 and received a straight-to-series order from USA Network. Like the Bourne films, Treadstone is filmed all over the world, including the United States, Budapest, Paris, Taiwan, Africa, and India, and boasts a cast comprised of American and international actors. In addition, Treadstone's story is ambitiously split into two timelines: the present-day events surrounding the Assets' reawakening and the events set in 1973 which involved the secret origin of the Treadstone program.
