Radka Kunderová, Principal Investigator of the "Theatre ReDefined" research project, interviews the German theatre scholar Erhard Ertel about the post-1989 developments in the former East German theatre. The interview discusses the period of the 1990s and the change of the theatre's social role after 1989 and German reunification. Erhard Ertel comments on e. g. differences in the former East and West German theatre landscapes, the relationship between the political and theatre and the status of the Volksbühne Berlin and Frank Castorf's theatre work in such a context.
