Harry Potter & the Order of the Pheonix

The trailer of the movie Harry Potter & the Order of the Pheonix is out! I saw the trailer on http://mugglenet.com and I'm so excited!! This time it will be totally different because previously I haven't read the books before I went into the cinema. This time I've read the book and my level of expectation is very high. I hope the crew don't mess up the movie :
