Fan Casting The Kane Chronicles (Live-Action)

The Kane Chronicles follows the story of Carter (14) and Sadie (12) Kane, and their discovery that they are the most powerful Egyptian magicians to be born in hundreds of years. As the Egyptian gods begin to awaken, the siblings must fight the forces of Chaos in order to maintain Ma'at. Please make sure your picks for the kid characters match their book-ages please! Also, please remember that Sadie is still mixed and half-black- I've seen *too* many ppl cast her as a completely white actress.
