Check out these new trailers of Harry Potter and the Order of Phoenix, scheduled to be released on July 13. These are better then the previous trailer which was released in a hurry long time back and was pretty disappointing.

At The Leaky Cauldron Video Gallery...

Both are different. So don't think that these are two links of the same video! I liked the one at Apple Movie Trailers more rather than the one below it. But both offer a glimpse of the movie in their own manner.
