He joins the "Twilight" star in the political drama written and directed by Peter Sattler
Set in the U.S. Military's Guantanamo Bay detention camp in Cuba, Stewart will play Cole, a soldier who strikes up a friendship with one of the young prisoners.
Soria will play the role of Rico, described as one of Cole's closest friends on the base. Very naive, maybe a little dim, Rico offers Cole support and backup when she needs it most.
Soria is a series regular on "Army Wives." He has also appeared on numerous television shows, including NBC's "Prime Suspect," CBS's "CSI: Miami," and Showtime's "Dexter."
On the feature side, he was in 2009's "Fast & Furious," "Hamlet 2" and "Crank: High Voltage."
Written and directed by Peter Sattler, the political drama is produced by Gina Kwon and Sophia Lin, and executive produced by David Gordon Green, Lindsay Williams and Ellen Goldsmith-Vein. Production begins later this summer.
Soria is represented by Defining Artists and David Dean Management.
