6. 82 Per-Cent of Michael Gambon.
Not kidding - this scarily lifelike replica of Dumbledore #2 is constructed at 82% scale, for reasons that were not immediately apparent (much like most of Dumbledore's plans).
Presumably the other 18% is in the form of a Horcrux somewhere else.
5. Animatronic Voldemort Fetus!
Minus the blood and guts he was covered in for his big reveal in Deathly Hallows Part 2, You-Know-Who-Has-No-Nose is even creepier, looking like the world's most evil baby. Press a button on the display in front of the cabinet, and his little heart starts beating, after which he stretches and writhes.
It's the most unpleasant-looking thing to be associated with Ralph Fiennes since Onegin.
4. 'Gon Today, Here Tomorrow.
No special knocks needed - this Diagon Alley is open to all, though the storefronts remain locked and their tempting windows full of desirable delicacies remain just out of reach. Sadly, the Gringotts facade is just that, as you'll have to bring your own Goblin Gold to even dream of affording some of the stuff in the gift shop...
If you have to ask how much, you don't want to know...
At the Weasleys' joke shop, this life-sized Garbage Pail Kid wannabe emits a steadily rotating stream of literal technicolor yawn, turning "spewing nonsense" into an amusing noun rather than a derisive verbal adjective.
2. Would a Skeptical Phoenix Feather Doubt Fire?
Every wand that was in Ollivander's shop in Diagon Alley had a potential owner's name on the box, and they were all different. But one in particular caught my eye...
Homealoneus! This, finally, is an explanation for how such a decidedly middle-of-the-road director continues to prevail - he's a wizard, Harry!
1. Whole Hog, Warts and All.
The grand finale of the tour is a scale model of the entire school of witchcraft and wizardry, built for the first film and featuring details as minute as individually crafted shingles on every rooftop. It is seriously huge, and yet still smaller than if you were to make a screen-accurate Hogwarts playset scaled perfectly to Lego minifigs.
But since it doesn't include the Whomping Willow, the debate about where the tantrum-throwing tree is actually located (real answer: depends which movie you consult) remains unsettled.
That the exhibit is worthwhile, however, should be unambiguous.
