Harry Potter fans will have to be sure they rush out to get their copies of any missing DVDs or Blu-Rays from their collections. As of December 29 of this year, Warner Bros. will stop shipping all copies of the films.

This surprise move will give fans only a two month window to go out and grab the latest in the series, "Harry Potter and the Deathly Hallows - Part 2", as well as the "Complete 8-Film Collection" box set. Both will be hitting shelves on November 11.

Disney Studios does the same thing with their animated titles. They release things for only a certain period of time before they are put back into "the vault".

Some say a special edition DVD or Blu-ray will be offered sometime next year or on 2013.Harry Potter Film.
