An exceptionally versatile character actor and occasional lead in features and television, Justin Theroux tackled both comedy and drama with equal deftness throughout his decade-plus career, and proved himself a talented comedy writer as well by penning the scripts for "Tropic Thunder" (2008) and "Iron Man 2" (2010). A handsome actor who seemed to prefer offbeat portrayals over leading man roles, he began his onscreen career in indies like "I Shot Andy Warhol" (1996) before moving effortless into Hollywood titles like "Romy and Michele's High School Reunion" (1997). He was adept at playing slick, soulless professionals, like an arrogant film director in David Lynch's "Mulholland Dr." (2001) and a business friend of Christian Bale's deranged Paul Bateman in "American Psycho" (2000), but could also play thoughtful, caring men, like his cerebral suitor who charmed Rachel Griffiths on "Six Feet Under" (HBO, 2001-05). Theroux's strongest suit, however, was offbeat comedy, and he mined that field on numerous occasions throughout his career in features like "Zoolander" (2001) and "Charlie's Angels: Full Throttle" (2003). He made a modest debut as a director on the indie drama "Dedication" (2006), but found greater success as a writer on the over-the-top comedy "Tropic Thunder" and the blockbuster "Iron Man 2." His dual status as favored actor and screenwriter made Theroux a genuine hyphenate, and one whose career appeared to be just accessing its upper reaches.
