This book transports young and old to the unique universe of a young prince and the journeys he takes to mysterious planets in his solar system. Now if that isn't the definition of movie magic, I don't know what is.
And OK, so maybe Gwen Stefani and Gavin Rossdale's son isn't officially an actor, but he's been around cameras long enough that he seems to be a natural. And he's basically grown up as an unofficial prince, so he'll be able to relate. But mostly, we want to cast him because he's downright adorable. I defy you to argue against his ridiculous degree of cuteness.
