One other thing. I was working at University Cinema 1&2 When Midway was released. There were always patrons that came out of the opposite theater when the surround effects went off asking if there were severe thunderstorms in the ares. Same timeframe movies - Mandingo, Happy Hooker, The Wind and the Lion (a personal favorite).
