Nudity in film is any presentation in films that includes at least one person who is nude or wearing less clothing than contemporary norms in some societies consider "modest". The presentation of nudity in films or otherwise has been controversial since the development of the medium, and most nude scenes in films have had to be justified as being part of the story, in the concept of "artistically justifiable nudity". In some cases nudity is itself the object of a film or is used in the development of the character of the subject. In some cases, nudity has been criticized as "superfluous" or "gratuitous" to the plot, and some film producers have been accused of including nudity in a film to appeal to certain audiences. Many actors and actresses have appeared nude, or exposing parts of their bodies or dressed in ways considered provocative by contemporary standards at some point in their careers.
Nudity in film should be distinguished from sex in film. Erotic films are suggestive of sexuality, and usually contain nudity, though that is not a prerequisite. Nudity in a sexual context is common in pornographic films, but softcore pornographic films generally avoid depiction of a penis or a vulva. A film on naturism or about people for whom nudity is common may contain non-sexual nudity, and some other non-pornographic films may contain very brief nude scenes. The vast majority of nudity in film is found in pornographic films.
Nude scenes can be controversial in some cultures because they may challenge some of the community's standards of modesty. These standards vary by culture, and depend on the type of nudity, who is exposed, which parts of the body are exposed, the duration of the exposure, the pose, the context, and other aspects. Regardless, in many cultures nudity in film is subject to censorship or rating regimes which control the content of films, with the intention of limiting content that is deemed by the classification authorities or the movie industry, or both, to be harmful or undesirable, morally or otherwise.
Many directors and producers apply self-censorship, limiting nudity (and other content) in their films, to avoid external censorship or a strict rating, in countries that have a rating system. Directors and producers may choose to limit nudity because of objections from actors involved, or for a wide variety of other personal, artistic, genre-bound or narrative-oriented reasons.
