So, I got my DVD of the HP movie, and I was playing with the stuff on Disc 2, and when you choose to enter Diagon Alley, there's a quick montage of appropriate visuals to take you there, including a chalk menu board from the Leaky Cauldron and guess what was on it - PICKLED EEL!!!! Pickled Eel is Freddy Shrike's favorite Wizard delicacy, and a running gag between him and Kevin, but I never knew till now that it was a "legit" HP reference. Ahahaha!
I got to the deleted scenes, with some help from my sister and a website, but my favorite part of disc 2 is in the Charms classroom, where you can watch the scene where the kids discuss Fluffy and Snape and Nicolas Flamel with Hagrid in several foreign languages. (Except, on the list of language choices, those languages that do not use the same alphabet as English are written in their own characters, and I don't know what they all are.)
