10 Foolproof Steps For A Perfect Harry Potter Remake
5. Plan Ahead
Rereading Harry Potter, it becomes immediately apparent that J.K. Rowling really did know what she was doing from the start. The first few books are littered with essential setup that adds real weight to later events. Because they didn't know where she was going at the time, however, the films missed out a lot of this, leading to fumbled alterations or interesting threads being dropped altogether.
My personal favourite is Dumbledore's Chocolate Frog card, which references his defeat of Gelert Grindlewald a whole seven books before that confrontation becomes an essential part of Voldemort's victory. Of course, in 2001 that was just extraneous background detail, whereas his relationship to Nicholas Flammel was plot essential, so it was cut. Whether this played a part in The Deathly Hallows never really going into Dumbledore's backstory or his relationship with the pre-Voldemort is unclear, but had it all been built correctly, it could have been a highly impactful throughline.
Now we know the full scope of Harry Potter a remake could so much more easily include these elements, and even restructure itself to better focus on retroactive important elements. This is where the Game Of Thrones parallel is its strongest, rewarding attentive repeat viewings.
This also chimes with non-plot elements, like the layout of Hogwarts; as much as it is prone to changing, having a basic castle that's designed to provide the setting for all key events down the line would make for a much cohesive overall whole.
