Go to the IMDB page for Harry Potter and the Sorcerer's Stone (or Philosopher's Stone, wherever you may reside). Now, click on the link that shows you all the release dates for the film. Now, scroll through the dates until you reach the very last one. Am I the only one seeing this?
Look at the dates for the rest of the series. Looks like they'll be re-releasing each of them to theaters for a single day. If you click the link for the year you will see Battle Angel, with a $200,000,000 budget, Star Wars: Episode VIII, and Robocops.
