In December 2007, Witherspoon began working with Vince Vaughn, filming the holiday comedy Four Christmases, a story about a couple who must spend their Christmas Day trying to visit all four of their divorced parents. The film was released in November 2008. Despite being panned by critics, the movie became a box office success, earning more than $120 million domestically and $157 million worldwide. In 2009, Witherspoon voiced Susan Murphy, lead character in DreamWorks' computer-animated film Monsters vs. Aliens, released in March 2009, becoming her biggest hit at the time. She also co-produced the Legally Blonde spin-off Legally Blondes, starring Milly and Becky Rosso.However, Witherspoon did not appear in a live-action film for two years after the 2008 release of Four Christmases. She told Entertainment Weekly that the "break" was unplanned, stating that, "I just didn't read anything I liked... There are a lot of really, really, really big movies about robots and things—and there's not a part for a 34-year-old woman in a robot movie." Witherspoon returned with three films released in 2010, 2011 and 2012, all centered on her as a woman caught in a love triangle between two men. In a 2012 interview with MTV, Witherspoon jokingly referred to this trio of films as her "love triangle period".The first film was James L. Brooks' romantic comedy How Do You Know which starred Witherspoon as a former national softball player who struggles to choose between a baseball-star boyfriend (Owen Wilson) and a business executive being investigated for white-collar crime (Paul Rudd). The movie was filmed in Philadelphia and Washington, D.C. during the summer and fall of 2009 and released on December 17, 2010. The movie was both a critical and box office failure. Despite a budget of more than $100 million the film earned only $7.6 million in its opening weekend, leading the Los Angeles Times to call it "one of the year's biggest flops". The movie earned mainly negative reviews from critics, scoring 35% on Rotten Tomatoes with 111 reviews as of late December 2010.Witherspoon's second love-triangle movie was the film adaptation of the 1930s circus drama Water for Elephants. She began circus training in March 2010 for her role as Marlena, a glamorous performer stuck in a marriage to a volatile husband (Christoph Waltz) but intrigued by the circus' new veterinarian (Robert Pattinson). The movie was filmed between late May and early August 2010 in various locations in Tennessee, Georgia, and California. It was released on April 22, 2011 and received mixed critical reviews.In September 2010, Witherspoon began principal photography in Vancouver for the third and final love-triangle film, This Means War, a 20th Century Fox spy comedy directed by McG in which Witherspoon's character is at the center of a battle between best friends (played by Chris Pine and Tom Hardy) who are both in love with her. The film had a "sneak-peek" release on Valentine's Day, before fully opening on February 17, 2012. The film was panned by critics (with a 25% Rotten Tomatoes rating), and fared poorly at the box office, taking fifth place on its opening weekend with sales of $17.6 million. The New York Times remarked that this "extended the box office cold streak for the Oscar-winning Ms. Witherspoon".
