Recently, I found out that the release date for Harry Potter and the Half-Blood Prince has been changed from 11/21/08 to 7/17/09. Every fan is angry about this, because it was done to make more money.

In the news on a Harry Potter fansite:

"In making the announcement, Mr. Horn stated, “Our reasons for shifting ‘Half-Blood Prince’ to summer are twofold: we know the summer season is an ideal window for a family tent pole release, as proven by the success of our last Harry Potter film, which is the second-highest grossing film in the franchise, behind only the first installment. Additionally, like every other studio, we are still feeling the repercussions of the writers’ strike, which impacted the readiness of scripts for other films—changing the competitive landscape for 2009 and offering new windows of opportunity that we wanted to take advantage of. We agreed the best strategy was to move ‘Half-Blood Prince’ to July, where it perfectly fills the gap for a major tent pole release for mid-summer.”
