According to the Associated Press, Warner Bros. head of distribution’s Dan Fellman reports that the release date for Harry Potter and the Half-Blood Prince was moved to July 15th from July 17th in the US and UK because: “Every day the kids are out of school in summer is just like an extra Saturday.”
How very true!
