Julia Fiona Roberts (born October 28, 1967) is an American film actress and former fashion model. She became well known during the early 1990s after starring in the romantic comedy Pretty Woman opposite Richard Gere, which grossed US $463 million worldwide. She won the Best Actress Academy Award in 2000 for her critically acclaimed turn as the title character in Erin Brockovich and earned Oscar nominations as Best Supporting Actress for Steel Magnolias (1989) and Best Actress for Pretty Woman (1990). Her films, which also include romantic comedies such as My Best Friend's Wedding, Mystic Pizza, Notting Hill, Runaway Bride, and crime films such as The Pelican Brief and Ocean's Eleven, have collectively earned box office receipts of over US$2 billion, making her the most successful actress in terms of box office receipts.

Roberts had become one of the highest-paid actresses in the world, topping the Hollywood Reporters annual "power list" of top-earning female stars from 2002 to 2005, until 2006, when Nicole Kidman won the top spot. Her fee for 1990's Pretty Woman was $300,000; in 2003, she was paid an unprecedented $25 million for her role in Mona Lisa Smile. As of 2007, Roberts' net worth was estimated to be US$140 million.

Roberts was the first actress to appear on the cover of Vogue and the first woman to land the cover of GQ. She has been named one of People magazine's "50 Most Beautiful People in the World" eleven times, tied with Halle Berry. In 2001 Ladies Home Journal ranked her as the 11th most powerful woman in America, beating out then national security advisor Condoleezza Rice and first lady Laura Bush. Roberts has a production company called Red Om Films ("Moder" spelled backwards; formerly Shoelace Productions).

Roberts made her film debut playing a supporting role opposite her brother, Eric, in Blood Red (she has just two words of dialogue), which, although completed in 1986, was not released until 1989. Her first television appearance was as a juvenile rape victim in the initial season of the series Crime Story with Dennis Farina, in the episode titled "The Survivor", broadcast on February 13, 1987. She also once appeared on Sesame Street opposite the character Elmo, demonstrating her ability to change emotions. Roberts first caught the attention of moviegoers with her performance in the independent film Mystic Pizza in 1988; that same year, she had a role in the fourth season finale of Miami Vice. The following year, she was featured in Steel Magnolias as a young bride battling diabetes and garnered her first Oscar nomination (as Best Supporting Actress) for her performance.

Roberts made her Broadway debut on April 19, 2006 as Nan in a revival of Richard Greenberg's 1997 play Three Days of Rain opposite Bradley Cooper and Paul Rudd. Although the play grossed nearly US$1 million dollars in ticket sales during its first week and was a commercial success throughout its limited run, most critics heavily criticized Roberts' performance. The New York Times' critic Ben Brantly, a self-proclaimed 'Juliaholic,' described her as being fraught with "self-consciousness (especially in the first act) [and] only glancingly acquainted with the two characters she plays." Brantley also criticized the production of “Greenberg's slender, elegant play,” writing that “it's almost impossible to discern its artistic virtues from this wooden and splintered interpretation, directed by Joe Mantello.” Three Days of Rain received two Tony Award nominations in stage design categories, but took home neither prize. Roberts did, however, receive a Broadway.com audience award (a minor theatrical prize) for her performance.
