I have all the HP books in hardcover, and have read them quite a few times.
I enjoyed the in depth report of the above DH I sceening.
I am curious as to why David Yates and the producer David Heyman and WB decided to
have a test screening. Chicago is a good, middle of the country to get a variety of viewpoints. I hope they are able to utlilize the audiences comments to improve or
tweak the film where needed. Great report!
