Process
Making a play means creating a lot of work that no one ever sees. Even social media ads.
The whole concept relied on these necessities: The audience could hear the real movie audio and see the actors listening to the same movie audio. The actors spoke only in English, in their natural, American accents. The characters they played were speaking German and only one of them understood English. For all the characters to understand the movie audio, the only one of them who understood English had to translate it in real time, aloud. The audience heard this translation as well. It was also in English.

So it sounds like it's being broadcast via an East German radio spying device.
