Why Alexa Rivera From Chicago P.D. Looks So Familiar

Lisa Vidal continued to appear in guest turns on major TV shows, showing up as Irma Levine on Season 2 of the ABC legal dramedy "Boston Legal." She also appeared on procedurals such as "Without A Trace" and "CSI: Miami" and had a brief role in the 2009 science-fiction blockbuster "Star Trek" as an unnamed Barracks Officer.

Vidal landed her next regular role in the NBC science fiction mystery series "The Event," which reunited her with Laura Innes and Blair Underwood. In the series, which focuses on aliens on Earth and the United States government's response to them, Vidal played Christina Martinez, the First Lady, and wife of President Elias Martinez, played by Underwood.

Throughout the show's first and only season, which began in 2010, Christina remains supportive of her husband as he discovers the presence of aliens kept captive by the government and elsewhere. When another senator brings up questions about Christina's past to Elias, she tells him her family came to the United States illegally. However, the series finale reveals that there's yet more to Christina's story than she ever told anyone.
