A new trailer for the upcoming Harry Potter and the Half-Blood Prince movie has been released, clocking in at one minute and thirty-two seconds. It shows much more than the previous U.S. teaser trailer did, featuring a longer clip of the “ring of fire” in the cave scene (when the Inferi attack), and many other previously unseen bits. A lot of things go by so fast that you won’t be able to see them very well unless you go through frame by frame, which many of you fanatics will undoubtedly do after watching the trailer for the first time.

The trailer is being called the “International Teaser Trailer,” though there is a possibility that it has been leaked, seeing as it says that the movie is coming “This Year” rather than “Summer 2009,” implying that the trailer was not ready for release. Unless Warner Brothers just made a mistake?
