The Berlin Theatertreffen is truly an Olympic event of German-language theatre. In accordance with its statutes, the festival invites the ten most remarkable theatre productions from Germany, Austria and Switzerland to Berlin in May every year. A jury of theatre critics has chosen productions from Berlin, Graz, Hamburg, Cologne, Munich and Vienna to participate at this year’s Theatertreffen 2010. The selection illustrates an increasing trend towards international co-productions. Transnational collaboration with directors from abroad is also becoming more common in German-language productions. For example, the Schauspielhaus Graz produced “Die Stunde da wir nichts voneinander wußten” [The Hour We Knew Nothing of Each Other], which was adapted and directed by Viktor Bodó in collaboration with his Szputnyik Shipping Company from Budapest, and the Vienna Burgtheater produced “Life and Times – Episode 1”, a play directed by Pavol Liska and Kelly Copper, the directors of the New York-based Nature Theater of Oklahoma. The festival opened with “Kasimir and Karoline”, a coproduction by the Schauspiel Köln and the Dutch theatres NT Gent and De Veenfabriek.
