One of the most challenging parts of any Stephen King adaptation is walking that fine line between childhood fears and adult terror. It is a perfect example: how do you take images meant to be frightening to 12 and 13-year-olds and adjust them for an adult audience? This is the formula that King has used to make him one of the most successful authors of all time, but stepping outside of the characters’ heads — and behind a movie camera — only ramps up the challenge of balancing tone just right. That’s why it’s been so heartening to hear It director Andy Muschietti say all the right things in pre-release interviews. For better or worse, it sounds like he really gets it.
