HBO’s Harry Potter remake will have the chance to include far more than the movies, but some after-the-fact additions to canon are better off left out. These details came from a mix of spinoffs and notes from the author, making the lore surrounding Harry’s story even more complete. Many of these helped us better understand the characters and their circumstances, while other big reveals felt disjointed. The Harry Potter remake will have an opportunity to incorporate these with the central story, and though some could be an asset to the HBO series, others would be a mistake to include.
