"This season of 'Graceland' took viewers on a wild ride with unexpected character twists, and a heart-stopping cliffhanger that left a lead character's fate in question," USA Network president Chris McCumber said in a statement. "Jeff Eastin and the talented ensemble cast deliver on all levels, and season three will undoubtedly continue to keep us on the edge of our seats."
The cast also includes Tony Award nominee Daniel Sunjata (Take Me Out) as the FBI's Paul Briggs, as well as Vanessa Ferlito, Manny Montana, Brandon Jay McLaren and Serinda Swan.
