Back in the mid-Eighties, a now sadly defunct movie theater here in Dallas used to run regular midnight screenings of Dawn, and we had an audience participation crowd that made Rocky Horror look sick. Part of the appeal was that we encouraged improvisation (at one point in late 1985, we had actual standup comedians hitting the show in order to keep in shape, and I was constantly adding such nightmares as, when a character is forced to shoot two child zombies, "When I say 'clean your room,' I MEAN clean your room!") and partly because most of the audience worked retail in the Dallas area. Around Christmas, we didn't need to pay $3.50 to watch crowds of mindless zombies bashing on the doors in an attempt to get in, because we lived it every morning when we came to work.
