Jon Hicks has a nice slideshow of typography from the Harry Potter and the Order of the Phoenix. (via waxy) Design Observer did a piece on the typography of Order of the Phoenix becoming its own character.
It is The Daily Prophet which emerges in this film as a secondary character, performing interstitial cameos made all the more exhilarating because the camera sweeps in and out, ricocheting off the page, magnifying and dramatizing a typographic vocabulary that combines a slightly mottled, letterpress-like display face with great portions of illegible calligraphy.
