Cameron Michelle Diaz

Diaz's only film of 2007 was Shrek the Third, the third installment in the Shrek franchise. Although the film was met with mixed reviews from critics, it grossed $798 million worldwide. The same year, Diaz also voiced Princess Fiona in a thirty-minute Christmas special, directed by Gary Trousdale. Diaz earned an estimated $50 million during the period of a year ending June 2008, for her roles in the Shrek sequel and her next film What Happens in Vegas opposite Ashton Kutcher. A romantic comedy by Tom Vaughan, Diaz and Kutcher portrayed two strangers who awaken together to discover they have gotten married following a night in which they won a huge jackpot after playing the other's quarter. While audiences reacted positively to the film, reviews were negative.
In 2009, she starred in My Sister's Keeper and The Box. Based on Jodi Picoult's novel of the same name, My Sister's Keeper was released to mixed reviews in June 2009. In the drama, Diaz plays a former lawyer and mother of two, one of whom is dying of leukemia. A moderate commercial success, it grossed $95 million worldwide, mostly from its domestic run. Set in 1976, The Box, written and directed by Richard Kelly, stars Diaz and James Marsden as a couple who receive a box from a mysterious man who offers them one million dollars if they press the button sealed within the dome on top of a box, knowing that someone, somewhere, will die from it. Critical response towards the psychological horror film was mixed, and, though having grossed its budget back, was considered a financial disappointment.

In 2010, Forbes ranked Diaz as the richest female celebrity, ranking her number 60 among the wealthiest 100. Also that year, Diaz reprised her voice role of Princess Fiona in Shrek Forever After, the fourth installment in the Shrek series. Although the film opened to mixed reviews from critics, it grossed a worldwide total of over $752 million and became the fifth top-grossing films released that year. Also in 2010, Diaz reunited with her Vanilla Sky co-star Tom Cruise in the action comedy film Knight and Day. In it, Diaz plays a classic car restorer who unwittingly gets caught up with the eccentric secret agent Roy Miller, played by Cruise, who is on the run from the Secret Service. Knight and Day received mixed reviews, and while the comedy performed poorly at the box office in its debut, it became a sleeper hit at the box office at a worldwide gross of $262 million.
