The genial, slightly stocky Hollywood character actor Kevin Dunn graced the casts of some of the highest grossing and most enjoyable A-listers of the '80s, '90s, and 2000s. With a pleasant (if unremarkable) countenance, this brother of Second City veteran (and onetime Saturday Night Live mainstay) Nora Dunn cut his chops playing everymen in American movies and one-shot television episodes. Kevin Dunn lacked the #92;sketch comedy background of his arguably more famous sibling but quickly chalked up an equally extensive resumé at about the same time. Dunn debuted on camera in the mid-'80s, with a recurring role on the series #92;comedy drama Jack & Mike (1986), co-starring Shelley Hack and Tom Mason, but Alan Parker's harrowing civil-rights #92;drama Mississippi Burning (in which he played Agent Bird) marked his first real breakthrough. From that point on, he became ever-present in such blockbusters as Ghostbusters 2 (1989), Blue Steel (1990), Only the Lonely (1991), Hot Shots! (1991), Chaplin (1992), and Dave (1993). Directors often cast Dunn as an emotional (or political) support to a heavy, such as his brief evocation of Nixon aide (and eventual Christian spokesperson) Chuck Colson in Oliver Stone's #92;biopic Nixon (1995), that of Lou Logan (opposite Nicolas Cage) in Brian De Palma's muddled, flawed #92;paranoid thriller Snake Eyes (1998), and that of Alex (alongside Sean Penn) in the #92;political drama All The King's Men (2006). In 2007, Dunn appeared in the blockbuster #92;action hit Transformers as Ron Witwicky, the father of lead actor Shia LaBeouf's character, Sam. Dunn also had a role in the underperforming Tom Cruise/Robert Redford/Meryl Streep #92;drama Lions for Lambs. In the fall of that year, Dunn found success on the #92;sitcom Samantha Who? as the father of the amnesia-afflicted main character (Christina Applegate). ~ Nathan Southern, All Movie Guide
