It may not make up for Harry Potter and the Half-Blood Prince being pushed back from a November release to a summer of 2009 release, but here's a bit of good news for young movie fans:

Hannah Montana: The Movie pushed up its release date by three weeks from May 1, 2009 to April 10, 2009. It will now compete against anime adaptation Dragonball and the Seth Rogen / Anna Farris comedy Observe and Report.
