Another hair mistake
Again, we have an instance that could have easily been avoided, and it doesn’t make sense why it wasn’t. Sure, it’s asking too much of any movie to be perfect. But here we have an easily correctable mistake that should have been noticed. From Harry Potter and the Philosopher’s Stone, we have a picture of Hermione with long, crimped hair up top. On the bottom, in the very same scene, Hermione now has completely straight here. Another oops moment.
