Languages of Belgium
Dutch is the official language of the Flemish Community and the Flemish Region (merged to Flanders) and, along with French, an official language of the Brussels-Capital Region. The main Dutch dialects spoken in Belgium are Brabantian, West Flemish, East Flemish and Limburgish. All these are spoken across the border in the Netherlands as well, and West Flemish is also spoken in French Flanders. Much like English, Flemish dialects have adopted much more French and other Romance vocabulary through mutual cultural exchange throughout history when compared with other Dutch dialects and as such they are not always readily intelligible for Dutch speakers outside Flanders. Words which are unique to Belgian Dutch are called "belgicisms" (as are words used primarily in Belgian French). The original Brabantian dialect of Brussels has been very much influenced by French. It is now spoken by a minority in the Capital region since the language of most inhabitants shifted during the Frenchification of Brussels.
Cinema of Belgium
Cinema of Belgium refers to the film industry based in Belgium. Belgium is essentially a bi-lingual country divided into the Flemish (Dutch-speaking) north and the French-speaking south. There is also a small community of German speakers in the border region with Germany. Belgium is further a federal country made up of three regions (the Flemish Region, the Walloon Region and the Brussels-Capital Region) and three language communities (the Flemish Community (Dutch-speaking), the French (i.e., French-speaking) Community and the German-speaking Community).
Due to these linguistic and political divisions it is difficult to speak of a national, unified Cinema of Belgium. It would be more appropriate to talk about Flemish or Dutch-language cinema of Belgium and Walloon or French-language cinema of Belgium.
