The audience scene in End Of Evangelion There are clips in EoE that look like this. I wonder where these clips come from. What are they watching/listening to?
The theater is a shot from one of the screenings of Death and Rebirth. I vaguely recall someone somewhere identifying which theater it was, but I can't find the post. This was part of an entire sequence of live-action shots near the end of the instrumentality portion of "End of Evangelion", the panning shot of the inside of the theater is both kind of a 4th wall as well as fitting in with the motif of the theater within instrumentality. Recall also from the last two episodes of the TV Series where instrumentality is heavily depicted as part of a theatrical set, like on a stage. Likewise, in EoE, we have a few shots, including a sequence in a sandbox, where there are those folding chairs seen from the end of the TV series. 

Another related note is that the "Death Threats" sequence during a similar live-action portion of instrumentality has some of the letters mention seeing Death and Rebirth at the theater.
