The Cineteca Nacional (the Mexican Film Library), near the Coyoacán suburb, shows a variety of films, and stages many film festivals, including the annual International Showcase, and many smaller ones ranging from Scandinavian and Uruguayan cinema, to Jewish and LGBT-themed films. Cinépolis and Cinemex, the two biggest film business chains, also have several film festivals throughout the year, with both national and international movies. Mexico City tops the world in number of IMAX theatres,[citation needed] providing residents and visitors access to films ranging from documentaries to popular blockbusters on these especially large, dramatic screens.
