Although Rubin-Vega is best known for originating the role of Mimi Marquez in the original Broadway production of "Rent" (1996-97), she was replaced by Rosario Dawson in the 2005 film version because of a pending pregnancy. In 2010, Rubin-Vega earned an Independent Spirit Award nomination for reprising her stage role in Jack Goes Boating, a relationship-driven character study that also marked co-star Philip Seymour Hoffman's directorial debut.
Rubin-Vega's other notable theater credits include "Anna in the Tropics," "The House of Bernarda Alba" and "Les Misérables." She also appears briefly in Sex and the City: The Movie (2008).
In this big-screen continuation of the hit series, Big proposes to Carrie, but the groom's cold feet threaten to ruin their relationship forever. Meanwhile, Miranda leaves Steve after he confesses to a fling, and Charlotte gets some big news.
