Yesterday, I was exercising to a couple of SyFy Channel end-of-the-world movies. Both involved stuff raining down on Earth and destroying cities -- meteors in one case, technobabble electrical phenomena in the other. In both movies, the hits were random, sudden, numerous, and unpredictable. In both movies, the main characters escaped death by running madly while zigging and zagging. Occasionally, one would yell, "Look out!" and pull the others in a different direction. This tactic did not work for all of the extras running around in the background.
From one of the movies, I learned that, despite walking for days on end in a semi-post-apocalyptic landscape, the pretty female had some secret way to keep her hair clean and her makeup fresh, and the rugged male lead was able to stay clean shaven. (Maybe he was a eunuch! No. That would have been a very different movie.) On the bright side, he wasn't wearing stupid facial stubble. His hair stayed clean, too. So did the clothes on both.
In the same movie, the female lead was wearing high heels when rescued by the male lead. After walking for days and then finding themselves in semi-abandoned Los Angeles, they didn't take the time to get her a pair of sensible running shoes for the remaining days of walking.
