Alice Sophia Eve (born 6 February 1982; age 33) is the actress who played an alternate Carol Marcus in Star Trek Into Darkness. Although the character was a civilian scientist in Star Trek II: The Wrath of Khan, the version played by Eve is a Lieutenant science division Starfleet officer serving aboard the USS Enterprise.  She also recorded the audiobook of the film. 
Born in London, England, Eve made her screen acting debut in the BBC's biographical movie Hawking, in which Benedict Cumberbatch starred as Stephen Hawking. Eve and Cumberbatch later worked together in the 2006 comedy Starter for 10 before reuniting for Star Trek Into Darkness, in which Cumberbatch portrayed the primary antagonist. In the 2006 crime comedy Big Nothing, Eve co-starred opposite Simon Pegg, with whom she also reunited on Star Trek Into Darkness.
Eve's first American-made film was the 2009 drama Crossing Over, in which she co-starred with Ashley Judd. The following year, Eve was seen in two major motion picture comedies: she had the female lead in She's Out of My League and a supporting role in Sex and the City 2. The latter film also featured Kim Cattrall and Willie Garson.
In 2011, Eve appeared on the HBO series Entourage in the recurring role of Sophia. Among the performers she worked with on this series were Melinda Clarke, Alan Dale and Malcolm McDowell. To date, Entourage has been her only foray into American television.
In 2012, Eve played the lead female role in the Edgar Allan Poe-influenced thriller The Raven and appeared as a young Agent O in the sci-fi comedy sequel Men in Black 3. The latter also featured appearances by Bill Hader, Marti Matulis and Keone Young. Eve's upcoming films include the drama Decoding Annie Parker (with Spencer Garrett and Bob Gunton) and the crime thriller Cold Comes the Night (featuring Erin Cummings and co-written by Oz Perkins).
