Buried underground safe from the nuclear war and its aftermath lies the City of Ember. Its builders made it self-sufficient, capable of sustaining a large community. But the lights are going out, the machinery is falling apart. Did the builders leave a way out? Can two teenagers find it before darkness falls for ever?

The star of this film is the City of Ember itself. A stunning portrayal not only of a working survivalist city, and and how people adapt as it stops working as it should, but also of the community that evolves underground. Worth viewing for that reason alone.

Bill Murray comes over brilliantly as the slimeball mayor, content to gorge himself on his private haul while the city declines and falls.
