Here’s a trailer for City of Ember, a fantasy film aimed at kids that I’d never heard of, but when I paused our TV and told my wife and daughter I wanted to see this trailer they jumped up and got all excited.

It’s based on a book series and is being produced by kid-friendly studio Walden Media. The movie stars Tim Robbins and Bill Murray and opens this fall. I’ll let the trailer tell you what the movie is about.
