The Hong Kong motion picture rating system (traditional Chinese: 香港電影分級制度; simplified Chinese: 香港电影分级制度; Jyutping: hoeng1gong2din6jeng2fan1kap1zai3dok6) is a legal system of movie screening and rating. An official government agency issues ratings for any movie that will be shown in Hong Kong movie theatres.
At the beginning of the film industry in Hong Kong, when the viewing of movies had no age restrictions, films were made under strict guidelines. For instance, movie characters were not allowed to get away with crimes, and sex scenes were not permitted. In 1986, with the release of John Woo's violent gangster movie A Better Tomorrow (later rated IIB), the general public became concerned about the influence films had on children. As a result, the Hong Kong motion picture rating system was established under the Movie Screening Ordinance Cap.392 on 10 November 1988. The purpose behind the law was to provide parents of minors a chance to prevent their children from being exposed to inappropriate materials, as well as to allow people to watch movies with content aimed towards adults.
The ratings were previously issued by the Television and Entertainment Licensing Authority (TELA), and initially provided three levels of ratings, which led the slang term "three-tier ratings" (Chinese: 三級制) to popular usage.
In 1995, the ratings were amended, creating three levels of main ratings, and two sub-ratings for one level.
According to the laws of Hong Kong, any movies that are intended to be shown in Hong Kong cinemas or released to the public via any videotape or disc formats must be screened by the Office for Film, Newspaper and Article Administration. The Office will then permit the movie to be released under their assessed level rating. Movie trailers intended to be shown inside the cinema hall or in cinema lobbies must also be submitted for classification. Only still films exhibited for non-commercial purposes (cultural, educational, instructional, promotional or religious) are exempt.
