An imposingly-built character actor who specialized in intense, often dangerous characters on both sides of the law, Michael Rooker rose to prominence in the late 1980s as a psychotic serial killer in "Henry: Portrait of a Serial Killer" (1986). Outfitted with an unwavering gaze and a granite jaw, Rooker was a natural for physically terrifying villains, but gave equally fine turns as world-weary cops, cowboys and tough patriarchs, all of which benefited from his dust-dry voice and uneasy smile. Rooker went on to tackle a number of memorable roles, playing disgraced Black Sox player Chick Gandil in "Eight Men Out" (1988), disloyal New Orleans prosecutor Bill Broussard in "JFK" (1991), and outlaw-turned-lawman Sherman McMasters in "Tombstone" (1993). For the remainder of the decade, he had supporting turns in a wide array of films like "Mallrats" (1995), "Rosewood" (1997) and "The Bone Collector" (1999), while in the new millennium he began having a stronger presence on television with guest spots on "CSI: Miami" (CBS, 2002-2012), "Numb3rs" (CBS, 2005-2010) and "Criminal Minds" (CBS, 2005- ). In 2010, Rooker was cast as racist zombie apocalypse survivor, Merle Dixon, on "The Walking Dead" (AMC, 2010- ), a high-profile role the multi-faceted performer eagerly sank his teeth into.
