Eamonn Walker

A stage-trained British actor who became a star in film and on television in his native country, Eamonn Walker made the successful transition to Hollywood where he rose to prominence as the incarcerated Muslim leader Kareem Said on the gritty HBO drama series "Oz" (1997-2003). Prior to his work on the popular program, Walker made a name for himself on British television with the sitcom "In Sickness and in Health" (BBC, 1985-1992) and the police procedural "The Bill" (ITV, 1984-2010). He had an acclaimed feature debut in "Young Soul Rebels" (1991) and stood out in the Jude Law thriller "Shopping" (1994), but it was "Oz" that alerted U.S. audiences to his talents. From there, he co-starred in films like "Unbreakable" (2000), "Once in the Life" (2000) and "Lord of War" (2005), though television offered the actor his choicest roles. He landed a string of short-lived series like "Justice" (Fox, 2006), "Kings" (NBC, 2009) and "Lights Out" (FX, 2011), while appearing in films like "The Messenger" (2009) and "The Company Men" (2010). By the time he landed on "Chicago Fire" (NBC, 2012- ), Walker was one of TV's most consistent working actors.
