Jacqueline McKenzie

A professional singer on the side, the actress Jacqueline McKenzie made her onscreen debut in the psychological classroom thriller "Wordplay" before emerging as one of the most captivating talents in her native Australia, starring in the 1992 neo-Nazi drama "Romper Stomper" as a drug addict opposite a young Russell Crowe. In rapid succession, the actress delivered chameleonic performances as an environmentalist on the comedic sci-fi miniseries "Stark," and as two separate women suffering from mental illnesses in "Halifax f.

p: Lies of the Mind" and the schizophrenic-love story "Angel Baby," the latter of which garnered her an award from the venerable Australian Film Institute. Based largely on her acting abilities, McKenzie was granted permanent residency in America, where her appearance as a scientist in 1999's genetically-enhanced-shark thriller "Deep Blue Sea" helped her land the lead role of the icy D.H.S. agent Diana Skouris on the cult sci-fi series "The 4400." In addition to returning to the series for three seasons, McKenzie contributed one of her songs, "Shy Baby," to its second-season finale. The actress counts among her many TV credits a recurring role on the internationally aired psychiatric-hospital drama "Mental" and guest spots on such series as "Hawaii Five-0" (2010) and "NCIS: Los Angeles."
