The decision was highly controversial, and some suggested changing the law under which it was rated 18.
The original X certificate, replacing the H certificate, was issued between 19 by the British Board of Film Censors in the United Kingdom.
In some countries, X is or has been a motion picture rating reserved for the most explicit films.
Films rated X are intended only for viewing by adults, usually defined as people over the age of 18 or 21.
There are very few English words that start with ⟨x⟩ (the fewest number of any letter).
When ⟨x⟩ does start a word, it is usually pronounced (e.g.The modern tradition of using x to represent an unknown was introduced by René Descartes in La Géométrie (1637).As a result of its use in algebra, X is often used to represent unknowns in other circumstances (e.g.People under 18 may not buy, rent, exhibit or view these films.The exhibition or sale of these films to people under the age of 18 years is a criminal offence carrying a maximum fine of ,500.X-rays, Generation X, The X-Files, and The Man from Planet X; see also Malcolm X).In the Cartesian coordinate system, x is used to refer to the horizontal axis.It may also be used as a typographic approximation for the multiplication sign.In mathematical typesetting, x meaning an algebraic variable is normally in italic type (), partly to avoid confusion with the multiplication symbol.The commission has some leeway in classification, it may for instance take into account the artistic qualities of a movie not to count it pornographic.Movies with an X rating may only be shown in specific theaters (which hardly exist nowadays in France); they bear special taxes and tax rates, including a 33% tax on revenue.
