The correct answer is 3: Erwin Piscator and Max Reinhardt because both Erwin Piscator and Max Reinhardt were significant figures in the development of Epic Theatre, along with Bertolt Brecht.
Here’s how they are related:
Erwin Piscator: He was a German theatre director and producer who is often credited with being a precursor and influence on Brecht’s Epic Theatre. Piscator's work in the 1920s, particularly his use of multimedia, political themes, and emphasis on the social function of theatre, heavily influenced Brecht's ideas.
Max Reinhardt: Although primarily known for his work in more traditional and expressionistic theatre, Reinhardt’s innovative staging techniques, use of space, and approach to theatre as a visual spectacle influenced many, including Brecht. Reinhardt's emphasis on the director's role as a creative artist helped shape modern theatre practices, which Brecht would later adapt for his own purposes.
