TOD:
I think I've mentioned this story before, but I missed the first 15 minutes of "The Queen" in 2007 because a dispute between two movie theatre patrons became so incensed, and starting drawing in those around them, with yelling and screaming, that the whole theatre became embroiled in it. With all the yelling, the movie was drowned out. Finally one (or both) of the parties was removed by the management (to the applause of the rest of us), but they refused to start the movie over.
After that, I vowed to watch movies only at home, and I have pretty much stuck to that.
