I consider myself a big Harry Potter fan. If you see the movie with me, I'll go point by point as to what was different in the book. I can recite curses. I have a replica of Voldemort's wand. I have theories on what I think Butterbeer tastes like. I have a crush on Lucius Malfoy, but it conflicts with my admiration for the Weasley twins. But apparently, I'm not a real fan.
Warner Bros' booth has Horcruxes and Deathly Hallows on display. Helga Hufflepuff's cup, Salazar Slytherin's ring, Rowena Ravenclaw's diadem nestled next to the Elder Wand and the Invisibility Cloak. Unfortunately, my photo is poor. My invisibility cloak picture is a total blur. This is because you are looking at something akin to a medieval shrine. Harry Potter fans were clustered around it, refusing to move. Anyone who stepped too close to the Abin Sur display, and threatened to merge into the impromptu line that had formed around Potter artifacts was severely reprimanded by preteens and their moms. Finally, Warner Bros representatives had to step in and plead with Potter fans that they move on once they took photos. You can't stay here forever. Move on. Take a photo and keep moving. Genuflect if you must but you can't stay all night. Even then, fans were loathe to budge.
