A well-respected and prolific stage actor throughout the 1990s, John Slattery broke into screen acting at the end of the 1980s and endured several failed series and guest spots in television movies and the occasional feature film. Recurring roles on a string of high-profile programs like "Will and Grace" (NBC, 1998-2006), "Sex and the City" (HBO, 1998-2004), "Ed" (NBC, 2000-04) and "Desperate Housewives" (ABC, 2004- ) made him a casting agent's go-to for flinty and occasionally unyielding authority figures. Appearances in major motion pictures like "Traffic" (2000), "Flags of Our Fathers" (2006) and "Charlie Wilson's War" (2007) preceded perhaps his most widely-recognized character, playing the hard-drinking, chain-smoking philanderer and advertising executive Roger Sterling on "Mad Men" (AMC, 2007- ). Exuding a devil-may-care attitude and old school charm, Slattery's performance earned him considerable acclaim and status as one of the show's favorite characters. Because of his newfound prominence, Slattery was rewarded with supporting turns in big movies like "Iron Man 2" (2010) and a profile that was finally on the rise.
