First Photo of Matt Damon on New 'Bourne' Movie Set

Matt Damon's back -- even if his shirt is not.

In this photo posted on Twitter by producer Frank Marshall, the actor strips down for what looks like a fight scene on the first day of filming the new "Bourne" film.

Although much about the movie remains under wraps, Damon resumes the titular role he last played eight years ago in "The Bourne Ultimatum" before handing off to Jeremy Renner.

Julia Stiles also returns, joining Alicia Vikander from "The Man From U.N.C.L.E.", Vincent Cassell and Tommy Lee Jones.

"Without giving too much of it away, it's Bourne through an austerity-riddled Europe and in a post-Snowden world,” Damon tells Buzzfeed. “It seems like enough has changed, you know? There are all these kinds of arguments about spying and civil liberties and the nature of democracy.”

The movie's due out in July 2016.
