OF COURSE they will show the audience and there will be audible applause. They want to capture how much this show is loved. There will be an audience tomorrow and you can sure as hell bet the audience will be noticed when they film closing night.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
