City of Ember (2008)

---

If you're into fantasies, adventure, it's a good film to watch. It has - of course - some predictable areas, but it also brings new ideas to this category. Although not main characters, among the actors in this movie, one can find Tim Robbins and Bill Murray.
It's a well weaved story of a town which exists deep under ground, isolated from any knowledge of another world besides it's own. Some of its inhabitants though still work a theory of getting out on their own, when the food begins to become a problem.
