Silas Weir Mitchell

A talented character actor often cast as crazies, Silas Weir Mitchell recurred on "The Practice" (ABC, 1997-2004) and "Nash Bridges" (CBS, 1996-2001) and made a fun cameo in "Rat Race" (2001) before breaking through as a baddie who terrorizes the wife and daughter of Jack Bauer (Kiefer Sutherland) on "24" (Fox, 2001-2010). Building on his momentum, Mitchell balanced wild-eyed intensity with comedy and heart in high-profile recurring roles as two lovably whacked-out prisoners: Haywire on "Prison Break" (Fox, 2005-09) and Donny Jones on "My Name Is Earl" (NBC, 2005-09). After recurring on "Burn Notice" (USA Network, 2007-13) and appearing in Rob Zombie's "Halloween II" (2009), the consistently employable Mitchell earned his showiest part thus far as Monroe, an urbane but quirky supernatural informant on "Grimm" (NBC, 2011-17). So popular was Mitchell as Monroe that he quickly became a thoroughly indispensable part of the series. Immensely talented and charismatic, Silas Weir Mitchell was able to make even the weirdest character lovable, leaving many critics and fans excited to see just what unpredictable characters Mitchell would embody next.
