Berlin has Germany’s highest concentration of cinemas with about 280 screens in 100 cinemas. In addition to the many multiplex theaters showing the latest blockbusters, there are lots of independent art house theaters catering to more demanding movie buffs. One example is the Arsenal at Potsdamer Platz, which has been run by the Freunde der Deutschen Kinemathek (Friends of German Cinema) for more than 30 years. The Arsenal has special screenings as well as retrospectives and experimental movies from many different countries in their original language. The Filmkunsthaus Babylon Mitte also focuses on non-mainstream movies and has retrospective programs. Independent theaters such as the beautiful Delphi Filmpalast and Broadway in Charlottenburg have combined to form the Yorck Kino Gruppe, consisting of 12 cinemas. The Odeon in Schöneberg and the Babylon in Kreuzberg are members of this group and often show original language versions of contemporary films.
