A retired journalist locks himself in his house to watch his favourite film “Casablanca” – but the world constantly interrupts him with a series of demands. In their partly performed, partly read stage play, the Theater im Keller ensemble presents one of a total of 13 works by Slovenian playwright Evald Flisar that they have produced in German so far. “Aquarium” is sophisticated and full of humour, a witty and bitter play in which intense, verbally and thematically complex dialogues and monologues literally flood the stage.
