No other work qualifies more for the predicate 'political theatre' than that of German director Christoph Schlingensief (Oberhausen, 1960). When 'political theatre' became increasingly arbitrary and theatrical, Schlingensief came up with a rather unusual remedy: he went to war against the vagueness of politics by completely overturning supposedly unambiguous certainties.

From his earlier films from the 1980s - in which Hitler, rapists and mass shooters indulge in orgasmic outrages - to his dramas for the Berlin Volksbühne in the 1990s - in which German icons like Rudi Dutschke, Helmut Kohl or Rosa Luxemburg were knocked off their pedestals in chaotic scenes - and his performances in public spaces (such as the 1997 Missions-Projekt für Junkies und Obdachlose in Hamburg's Central Station), there is always one basic salient theme: trust no certainties!
