Hecate has an interesting series of posts on this auspicious event.
Then there's the question which new movie best would match the necessary celebrations of the day. My favorite is Snakes on a Plane, for obvious reasons, but it's coming out too late:
Another with profit potential is ``Snakes on a Plane'' in August, from the New Line Cinema unit of New York-based Time Warner, the world's biggest media company. The over-the-top thriller about poisonous snakes let loose on a passenger jet already is getting good word-of-mouth on the Internet, Pandya said. It's scheduled for release Aug. 18.
The word-of-mouth on the Internet is because it might be a really bad movie and that's interesting. And nobody has given me any money for mentioning this movie.
