If think you know what will happen in the movie simply because you've read the book, think again. Many times the events on the screen wildly deviated from those written in our well worn and tattered pages of HP 6. I'll refrain from too much detail, but my 10 year old son and I were somewhat disappointed when the Dursley's didn't even make an appearance! We really wanted to see them getting whacked on the head with glasses of mead. The movie keeps to the basic story line, but many of the details have been changed. Overall still an excellent experience.
