Actor Name: Diego Klattenhoff

Diego Klattenhoff stars as FBI agent Donald Ressler on AXN’s high-action government crime thriller “The Blacklist.”

With distinguished roles in a variety of projects, Klattenhoff is currently a series regular on the Golden Globe-winning and Emmy-nominated series “Homeland” as Maj. Mike Faber, best friend to Nicholas Brody (Damian Lewis).

Prior to his role in “Homeland,” Klattenhoff’s big break came when he was cast to play Shane Oman in the cult classic movie “Mean Girls,” where he collaborated with Tina Fey, Amy Poehler, Rachel McAdams, Amanda Seyfried and Lindsey Lohan. Since then, Klattenhoff has consistently worked on several films, including: “The Dry Land,” “Lucky Number Slevin” and “The Informers.”

Klattenhoff is currently starring in the just-released sci-fi thriller “Pacific Rim,” directed by Guillermo del Toro. The film is set in a world where soldiers piloting giant robots battle against monsters that have mysteriously risen from five miles beneath the ocean.

On the small screen in addition to “Homeland,” Klattenhoff has had memorable guest and recurring character appearances in series such as “Men in Trees,” “ER,” “Mercy,” “Smallville,” “Supernatural” and “Falling Skies.”
