Box Office Mojo has the release date for '
Order of the Phoenix' listed as July 13th 2007.
The last
official word we heard on the issue came ten days ago from David Heyman who said the release date was slated for either Summer or Autumn 2007. It is also still early days; '
Order of the Phoenix' has only been filming for about 2 months.
As such this 'release date' remains a rumour until it is confirmed or denied by WB.
