TV Line is reporting that Larisa Oleynik is joining the Hawaii Five-O as series regular.
On CBS’s reboot of the classic cop show, Oleynik will play Jessica Kaye, an ex-CIA analyst and Harvard graduate with a degree in Political Science and a Masters in Global Security and Intelligence Studies who is fresh off the plane from Langley, Virginia.
Her purpose in Hawaii? To assist Five-0 in the pursuit of Steve McGarrett’s arch nemesis, Wo Fat (Iron Chef America‘s Mark Dacascos). Jessica has a personal stake in the manhunt since Wo Fat was responsible for the murder of her fiancé, a well respected CIA field agent.
Oleynik’s role is recurring for the remainder of this season, with an option to become a series regular come Season 2. Oleynik, who rose to fame in the mid 1990s as the star of Nickelodeon’s The Secret World of Alex Mack, also recurred on NBC’s 3rd Rock from the Sun. She most recently guest-starred on AMC’s Mad Men as Ken Cosgrove’s fiancée.
