Bollywood is the informal term popularly used for the Hindi-language film industry based in Mumbai (formerly known as Bombay), Maharashtra, India. The term is often incorrectly used to refer to the whole of Indian cinema; it is only a part of the total Indian film industry, which includes other production centers producing films in regional languages. Bollywood is the largest film producer in India and one of the largest centers of film production in the world.

Bollywood is formally referred to as Hindi cinema. There has been a growing presence of Indian English in dialogue and songs as well. It is common to see films that feature dialogue with English words (also known as Hinglish), phrases, or even whole sentences.

The name "Bollywood" is a portmanteau derived from Bombay (the former name for Mumbai) and Hollywood, the center of the American film industry. However, unlike Hollywood, Bollywood does not exist as a physical place. Though some deplore the name, arguing that it makes the industry look like a poor cousin to Hollywood, it has its own entry in the Oxford English Dictionary.

The film industry consists of the technological and commercial institutions of filmmaking: i.e. film production companies, film studios, cinematography, film production, screenwriting, pre-production, post production, film festivals, distribution; and actors, film directors and other film crew personnel.

Though the expense involved in making movies almost immediately led film production to concentrate under the auspices of standing production companies, advances in affordable film making equipment, and expansion of opportunities to acquire investment capital from outside the film industry itself, have allowed independent film production to evolve.

The major business centers of film making are in the United States, Nigeria, Hong Kong and India. In Europe, France and United Kingdom are the countries that lead movie production .

Distinct from the centers are the locations where movies are filmed. Because of labor and infrastructure costs, many films are produced in countries other than the one in which the company which pays for the film is located. For example, many U.S. movies are filmed in Canada, the United Kingdom, Australia, New Zealand or in Eastern European countries.

Not to be confused with pornographic actress Sunny Lane.

Leone was born in Sarnia, Ontario to Sikh Punjabi parents from India. Her father was born in Tibet and raised in Delhi, while her mother (who died in 2008) was from a small town named Nahan in Sirmaur, Himachal Pradesh. As a young girl, she was very athletic and played street hockey with the boys, enjoyed ice skating on a nearby frozen lake and drinking hot chocolate in front of a fire after playing in the snow all day.

Though she was raised as a Sikh, her parents enrolled her in a Catholic school, as it was felt to be unsafe for her to go to public school. There she had her first kiss at 11, lost her virginity to a basketball player at another school at 16, and discovered that she was bisexual at 18. When she was 13, her family moved to Fort Gratiot, Michigan, then to Lake Forest, California a year later, fulfilling her grandparents' dream that the family be together in one place. She graduated from high school in 1999 and enrolled in college.
