It might have been a mistake to watch this film in our cold non-centrally heated house, especially the 2nd half where the entire northern hemisphere is frozen over.
We had to bring our small fan heater downstairs so we got a gentle waft of warm air blowing over us during the film. Warmth shouldn't be a luxury in modern england but that's how it feels in our current house.
Back to the film - it's quite surprising that it actually got made when you realise that Fox was one of the production companies behind it. Global warming denier Dubya friendly Fox (although he's now changed his tune slightly since).
