After nearly a decade working her way up the ranks from guest actress to regular player, Christina Hendricks finally made her mark as Joan Holloway, the curvaceous, titian-haired secretary with many tricks up her sleeve, on AMC's Emmy-winning period series, "Mad Men" (2007- ). Channeling screen sirens from the 1950s, Hendricks earned praise for her performance while becoming a role model for full-figured women, thanks to her oft-discussed hourglass figure that harkened back to the days of Marilyn Monroe and Ava Gardner. Prior to her breakthrough on "Mad Men," she cut her teeth in episodes of "Undressed" (MTV, 1999-2002) and "Angel" (The WB, 1999-2004), before landing her first significant part as a career-climbing intern on the showbiz satire "Beggars and Choosers" (Showtime, 1999-2001). From there, Hendricks appeared on Joss Whedon's short-lived cult hit "Firefly" (Fox, 2002-03) and the equally brief drama "Kevin Hill" (UPN, 2004-05), while guest starring on more stable shows like "Without a Trace" (CBS, 2002-09) and "Cold Case" (CBS, 2003-2010). But everything turned on a dime after Hendricks was cast on "Mad Men," leading to widespread acclaim and awards nominations, as well as career-expanding feature roles in "Drive" (2011) and "I Don't Know How She Does It" (2011). Whether playing a demure waif or a smoldering vixen, the always striking Hendricks defined a new style of old-school glamour while bringing her finely honed skills to every role.
