Versatile performer Jeffrey DeMunn was among a select group of stage, screen and television talents who defined the term "character actor." For over three decades, he moved effortlessly between roles as varied as Harry Houdini in "Ragtime" (1981) and playwright Clifford Odets in "Frances" (1982) to a fiendish serial killer in "Citizen X" (HBO, 1995) and a zombie hunter on "The Walking Dead" (AMC, 2010- ). His extensive theatrical background, which included a Tony-nominated turn in "K2" (1983), brought a strength of presence and oratory to his screen turns, making him a favorite for complex figures of authority like doctors, lawyers, professors and fathers of all moral stripes. He was a particular favorite of writer-director Frank Darabont, who cast him in nearly all of his films, as well as audience members who appreciated his apparently limitless skills, even if his name escaped them.
