So, a teaser trailer for Harry Potter and the Half-Blood Prince was released in Imax theaters before The Dark Knight. And this is what it shows:
That's right. A whole lot of NOTHING. Come on, Warner Brothers, give us some Ron Weasley in his Quidditch uniform. Some Harry and Dumbledore in the cave. Some Hermione attacking Ron with canaries. Some Fred and George Weasley. ANYTHING.
Also, yesterday was the one year anniversary of the release of Harry Potter and the Deathly Hallows. It really doesn't feel like a year.
