Answer:
The audience
Step-by-step explanation:
When staging a play from an former time, the element of the original production which is impossible to recreate or reproduce is the audience.
Audience in this context means the assembled spectators or listeners at a public event such as a play, film, concert.
The essence of staging a play is majorly the interaction or interplay between the performer and audience.
Staging a play needs to be experienced live. There is a "call and response" atmosphere that is not witnessed in a movie theater.
During the act of staging a play, when the audience laughs out loud, or cries, then the actors subsequently respond to that energy, which is not so in a movie because only reactions from the audience is witnessed.
