I was amazed that following the AWESOME battle scene with Valdemort (which we were watching in 3D IMAX - OMG - it was 15 minutes of awesome)...but anyway, SilverSon leans over and says:

"in the book, that scene was much longer...the did this...and this...and so on"

Geez...it told me he really did read it, but more so, he remembered it!
