“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.”
I'm calling bullshit Warner Bros. Are you listening to me? You just want to make more money (though really, why am I surprised?). And though you claim a summer release would allow you "to reach the widest possible audience," it's still bullshit. So kids are out of school in the summer? So what! November 21 was just one frakkin' week before Thanksgiving. And with the Harry Potter fandom, there still would be lots of money being made.
Call me a pissed off fan if you want (because I am, I'll admit it), but this is stupid. If you had said, it's just not going to be ready that I could accept. But not this. Not to wait 8 months. So, Warner Bros. you've been weighed, you've been measured, and you've been found wanting.
