Haven't seen the trailer for the next Harry Potter movie? Go here to choose a high/med or low resolution to view. Great trailer that shows how much the kids have grown up over the course of the four movies, a bit of the showdown between the Triwizard Tournament contestants, plus a look at Harry's battle with the dragon--spectacular special effects. Mugglenet also has some behind-the-scene video footage to download here.
Personally, I can't wait to see what this movie will look like as book four has been my favorite so far.
