Actor Jon Bernthal went to great lengths to learn his craft, moving from his native Washington, D.C., to Russia where he attended the Moscow Art Theatre School. Following his return to the U.S., Bernthal then obtained his M.F.A. from Harvard University's Institute for Advanced Theatre Training at the American Repertory Theatre. After graduating, he pursued a career in theater, appearing in numerous Broadway and off-Broadway plays, before he began transitioning into onscreen work with appearances on shows like Boston Legal and Law & Order: Criminal Intent. In 2006, Bernthal was cast in a starring role on the short-lived CBS sitcom The Class, after which he appeared alongside Elijah Wood in the indie feature Day Zero.

Berenthal scored the part of Al Capone in the sequel to the mega-successful Night at the Museum, and he had his most high-profile success to that point in 2010 when he was cast as Shane in the AMC zombie series The Living Dead. He also appeared in Oren Moverman's sophomore film, the cop drama Rampart.
