The first of this year’s invited productions, Das Werk/Im Bus/Ein Sturz, is actually three shorter plays, written by Austrian playwright Elfriede Jelinek and directed by Karin Beier, artistic director of Schauspiel Köln. The third piece, Ein Sturz, has water in it. A lot of water. Yesterday, before the premiere, I got the chance to sit in on a technical rehearsal on the main stage. I tried to capture a bit of that experience on film.
