Well, those are words that everyone wants to hear when it comes to fandoms, haha! Though we have to keep in mind that no film 
adaptation can be the exact same as the book it’s based off of, we can always hope that it gets as close as it can possibly get. Edward Zo (one of the many who auditioned for the role of Magnus Bane) has said that, as a fan of the books, he’s excited to see the book brought to life, and is really pleased with how the script remained faithful to the story.
Zo didn’t get the role because he was playing much younger than what casting was looking for. But casting for Magnus will be happening this week. We will hear news about casting in about two weeks!
