Hidden in the courtyard of the Kunstquartier Bethanien on Mariannenplatz in Kreuzberg is Berlin's oldest and only OmU (Original Version with Subtitles) open-air cinema. If you want to see international arthouse gems, cult classics, and current cinema highlights under the open sky, this is the place to be. A deckchair, a woolen blanket, and a beer: summer cinema doesn't get much better than this.
