Many fans of a certain boy wizard have already bought tickets to Harry Potter and the Half-Blood Prince, opening Wednesday at 12:01 a.m. in theaters across the land. But have you considered this: This is the sixth film in the series. The last one came out two years ago. The first came out eight years ago. Have you faithfully watched and re-watched the movies enough to be up-to-speed for Half-Blood Prince? Or will you be as lost as a muggle in a wand store?

Sure, you could refresh your memory by watching the DVDs, but where's the fun in that? Carmike Cinemas is hosting an event this Tuesday at about 65 of its theaters where all five films will be screened back-to-back, starting at 9 a.m., leading up to a midnight screening of Half-Blood Prince. The cost is only $15 for all five (you have to buy your Half-Blood Prince ticket separately), and you get to enjoy the films on the big screen, surrounded by the other Potterphiles in your community who don't have jobs.

Not all the Carmikes are doing this, so check out the list on the company's website to see if there's one close to you. Don't just show up at 9 a.m. at your nearest Carmike wearing a quidditch uniform. Most of the participating locales are in the Southeast quadrant of the U.S., though a few are scattered elsewhere, too. If you go, be sure to tell us about it in the comments, especially if anything crazy happens like Dementors showing up and sucking everyone's souls.
