What questions would you like the series to answer?
These shouldn't be considered as canonical info after all, I think, but everyone probably has some interesting facts they'd like to know.
My propositions:
- Will they somehow explain where was Harry and Hagrid for whole day, before arriving on Privet Drive? (remember that wizards were partying all day)
- Will Hogwarts again have moving staircases?
- Will the secret of Philosopher's Stone and Dumbledore's preparations (and the visit to the Flamels) be shown simultaneously in real time or as flashbacks?
