The cinema of the United States, also known as Hollywood, has had a profound effect on cinema across the world since the early 20th century. Its history is sometimes separated into four main periods: the silent film era, classical Hollywood cinema, New Hollywood, and the contemporary period. While the Lumiere Brothers are generally credited with the birth of modern cinema, it is undisputably American cinema that soon became the most dominant force in an emerging industry. Since the 1920s, the American film industry has grossed more money every year than that of any other country.

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's sixth-highest.

She has starred in other films, including Panic Room (2002), Zathura (2005), In the Land of Women (2007), The Messengers (2007), Adventureland (2009), The Runaways (2010), and Snow White and the Huntsman.

Her mother, Jules Mann-Stewart, is a script supervisor originally from Maroochydore, Queensland, Australia. She has an older brother, Cameron Stewart, and an adopted brother, Taylor. Stewart attended school until the seventh grade and then continued her education by correspondence. She has since completed high school.

Her whole family all worked behind the camera and Stewart thought she would become a writer/director, but never considered being an actor. "I never wanted to be the center of attention – I wasn't that 'I want to be famous, I want to be an actor' kid. I never sought out acting, but I always practiced my autograph because I love pens. I'd write my name on everything." Stewart's acting career began at the age of eight, after an agent saw her perform in her elementary school's Christmas play. After a year of auditioning, Stewart's first role was a small nonspeaking part in the Disney Channel original film The Thirteenth Year. Then, she had another part in the film The Flintstones in Viva Rock Vegas as the "ring toss girl". She subsequently appeared in the independent film The Safety of Objects, in which she played the tomboy daughter of a troubled single mother (Patricia Clarkson). Stewart also played a tomboy in the film Panic Room, playing the diabetic daughter of a divorced mother (Jodie Foster). She was nominated for a Young Artist Award for her performance.
