That's good news. Saving it for closer to Halloween seems like a good idea, anyway. I was worried this was just passed over because Blazing Saddles is more accessible for some reason. Wonder if they plan for the original Producers as well.
That said, while I'm glad they showed Willy Wonka for the kiddies, Gene is easily the only good thing about that film for me. As I've said before, I hate both films ...well, not hate so much as they both pail in comparison to the original novel and both versions are tainted by the time they were produced (Willy Wonka looked like H.R. Puffenstuff puked all over the factory, the Tim Burton version is too Tim Burton Fangirly). Gene was far superior to the rest of the film and he didn't need be. He is my favorite of the two Wonkas, most definitely. Still, read the book, you won't be sorry.
As for parodies of Wonka, my favorite is the Word Girl episode. Mainly because instead of taking the obvious route, they decided to make their expy, Zachary Zany, a stingy, tightfisted, joyless corporate exec who points out how that isn't even his real name and it's all marketing. Then giving insanely small samples to the factory tour guests. And yeah, Fry and the Slurm Factory and Wasted Talent...but Word Girl was the most creative of the lot.
