I went with my friends to see Return of the Jedi at a movie theater in Westwood, CA back in 1983 when I was 11. The trailers before the movie sounded fine, but when the movie started, for some reason, the volume was cranked to max. It was so loud, many of us were covering our ears and screaming, "TURN IT DOWN!!!" Some people left to tell the management, while most of us stayed there covering our ears but still watching because dude--it's Return of the Jedi and we just waited in line for like an hour, lol. After about 10 minutes of the movie, the volume suddenly reverted to a normal volume level. All good, right? WRONG. People were PISSED, and got up to insist that they restart the movie from the beginning. Of course, management was worried about their schedule and messing up the next showing. Then one guy started chanting "REFUND", and a bunch of the audience joined him so that even those who wanted to watch the movie couldn't. The manager went to the front of the screen, had the movie stopped, and promised us that they would indeed rewind the film and start the movie over. That's the first and only time I've been a part of a theater malfunction, and it was during an iconic movie. =)
