Bodyguard is a 2011 Indian romantic action film directed by Siddique. The third remake of the director's own 2010 Malayalam film of the same name, the film was produced by Atul Agnihotri and features Salman Khan and Kareena Kapoor in the lead roles. It also stars Raj Babbar, Mahesh Manjrekar and Hazel Keech in supporting roles. The film's first look and theatrical trailer was unveiled on 21 July 2011. Bodyguard was released on tiwar 31 August 2010 across 40 screens in 70 Indian cities and with 482 prints across the overseas territory.

The film broke many records upon its release. Within the first day of its release, it went on to become the highest opening day grosser as well as the biggest grosser ever for a single day up until then. The film set another box office record, netting 100.10 crore (US$19.97 million) in its first week, thus becoming the highest opening week grossing Bollywood film. Various sources estimate the worldwide gross of the film at 495 crore (US$98.75 million) and 685 crore (US$136.66 million), making Bodyguard one of the top three grossers without adjusting for inflation in Bollywood and the second highest-grossing Bollywood film of all time. After its theatrical run, it became the highest-grossing Bollywood film of 2011.

A bodyguard (or close protection officer) is a type of security operative or government agent who protects a person or persons — usually a public, wealthy, or politically important figure(s) — from danger: generally theft, assault, kidnapping, homicide, harassment, loss of confidential information, threats, or other criminal offences.

Most important public figures such as heads of state or governors are protected by several bodyguards or by a team of bodyguards from an agency, security forces, or police forces (e.g., in the U.S., the United States Secret Service or the State Department's Diplomatic Security Service). In most countries where the Head of state is and have always been also their military leader, the leader's bodyguards have traditionally been done by Royal Guards, Republican Guards and other elite military unit. Less-important public figures, or those with lower risk profiles, may be accompanied by a single bodyguard who doubles as a driver. A number of high-profile celebrities and CEOs also use bodyguards.

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.

Standard Hindi, or more precisely Modern Hindi, also known as Manak Hindi (Devanagari: मानक हिन्दी; meaning "Standard Hindi"), High Hindi, Nagari Hindi, and Literary Hindi, is a standardised and sanskritised register of the Hindi-Urdu language based on the Khariboli dialect of Delhi and Western Uttar Pradesh. It is one of the official languages of the Republic of India.

Colloquial Standard Hindi is mutually intelligible with another register of Hindustani language called Urdu. Mutual intelligibility decreases in literary and specialized contexts which rely on educated vocabulary. Due to religious nationalism and communal tensions, speakers of both Hindi and Urdu frequently assert that they are distinct languages, despite the fact that native speakers generally cannot tell the colloquial languages apart. The combined population of Hindi-Urdu speakers is the fourth largest in the world. However, the number of native speakers of Standard Hindi is unclear. According to the 2001 Indian census, 258 million people in India reported their native language to be "Hindi". However, this includes large numbers of speakers of Hindi dialects besides Standard Hindi; as of 2009, the best figure Ethnologue could find for Khariboli dialect was a 1991 citation of 180 million.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
