It is alright if the name Andrea Riseborough seems a little unfamiliar. Though the actress has been a rising star in her native England for years, beginning with her role as an ambitious Labour Party researcher on the political satire "Party Animals" (BBC Two, 2007), the Royal Academy of Dramatic Art graduate has only appeared on American audiences' radars since 2011, when she portrayed American divorcee and future Duchess of Windsor Wallis Simpson in Madonna's divisive "W.E." But those intervening four years found the preternaturally observant Riseborough pack in several memorable performances: she earned a BAFTA nomination for her nuanced turn as a young Margaret Thatcher in the made-for-TV movie "Margaret Thatcher: The Long Walk to Finchley" (BBC 4, 2008); was cast as a strong-willed factory machinist in the union drama "Made in Dagenham" (2010); and found the strong heart of a naively trusting wife in the 2010 remake of Graham Greene's "Brighton Rock." Her affinity for portraying determined women matched up perfectly with her role as Wallis Simpson, whose romance with King Edward VIII caused him to abdicate his throne in 1936 so they could marry. The film's controversial reception did nothing to slow the thoughtful actress' burgeoning career, however, and in 2012 she earned critical acclaim for her role as an IRA-member-turned-informant in "Shadow Dancer," set in '90s Belfast. Her next role, as a mysterious drone supervisor opposite Tom Cruise in the big-budget "Oblivion" (2013), highlighted her ability to shift from intense period piece to glossy Hollywood sci-fi. With a startling intensity and wise-beyond-her years talent, Andrea Riseborough is one to watch.
