Late last month a bunch of children were likely scarred for life by a little event called “Willy’s Chocolate Experience.” Who’s Willy? Wonka, of course — the subject of the recent hit movie Wonka. The Glasgow, Scotland-held event, with its carefully-worded title, wasn’t actually an official spinoff from the estate of Roald Dahl. Far from it. Instead it was a modestly festooned cheapo cash-in that left kids crying and parents instigating such a revolt that police had to be summoned. The fiasco has already inspired a forthcoming horror film. Now it’s getting a musical.
