The sixth movie in the franchise, based on the book by the same name, won't be shown in IMAX until July 29, two weeks after the film's July 15th opening.
Who do you need to Avada Kedavra?
The Autobots. (Will the Killing Curse even work on large, transforming robots?)
Half-Blood Prince was originally slated for November of last year, but Warner Bros. moved it to July 2009 in wake of the writers' strike. But the schedule shuffling placed Harry Potter squarely in the sights of the summer's other big sequel -- and its IMAX run.
But the rest of us will have to wait a couple of weeks for the 12 minutes of 3-D footage that are in the IMAX version.
The loss of those oversized IMAX ticket prices could affect Half-Blood Prince's opening weekend take.
But it could also boost the movie's overall gross -- most hardcore fans, not wanting to wait until July 29, will pay twice. However, those fans are likely to see the movie multiple times anyway. More casual moviegoers who would have otherwise opted for an IMAX showing are not likely to do the same.
