Filming of "The Architects" began on October 2, 1989, just one month before the German Reunification. For the crew, November 9 (the day the Berlin Wall fell), was a regular day at work. Having chosen to ignore ambiguous radio announcements in order avoid getting behind on the filming schedule, they didn't learn of the events until later that evening.
Established DEFA Director Hermann Zschoche turned down the offer of directing the material for "the Architects" because he knew how eager Peter Kahane was to do the job.
