The upcoming "Bourne" spinoff TV series "Treadstone" has found its two of its leads.

Jeremy Irvine ("War Horse," "Mamma Mia 2") and Brian J. Smith ("Sense8") have joined the cast of the USA series, which is inspired by the series of Matt Damon films (and Robert Ludlum novels). Here's the "Treadstone" breakdown, per Deadline:

'Treadstone' explores the origin story and present-day actions of a CIA black ops program known as Operation Treadstone — a covert program that uses behavior-modification protocol to turn recruits into nearly superhuman assassins. The first season follows sleeper agents across the globe as they’re mysteriously “awakened” to resume their deadly missions.

Irvive will be playing J. Randolph Bentley, a spy dispatched by the CIA to eliminate a key target, but ends up embroiled in an international conspiracy. Smith is starring as Doug McKenna, an all-American oil-rig worker whose life changes after he discovers long buried truths about himself.

USA picked up the show with a straight-to-series order earlier this summer. "Treadstone," created by "Heroes" mastermind Tim Kring, is set to begin production sometime in 2019. No word yet on a premiere date.
