You and dsikula are right. There was an abundance of caution around this capture. Crew are usually on top of each other during captures like these Backstage areas and alleys where gear is kept are cramped. The unfortunate circumstances around Covid opened up sister theaters, Golden and Booth. It was a wise decision to use them.
In addition to other precautions, every audience member had to provide proof of vaccination status and had to be tested prior to attending. Audience members were also isolated in pods of 2 and 4 people. All masked.
