The Day the Earth Caught Fire (1961)- it’s getting hotter (because simultaneous nuclear tests at Arctic and Antarctic have accidentally spun the Earth closer to the sun). Will everyone fry? Can the situation be saved? Great scenes of water rationing in London – superior English b-movie.
The Arrival (1996) – Charlie Sheen as a scientist?! There’s a scene where Charlie tells the terraforming alien that “turning the Earth into a hothouse for profit is immoral.” The alien shrugs his shoulders and says “we’re merely accelerating a process you lot are aware of and are doing nothing about.”
Soylent Green (1973) – Charlton Heston. Murder, intrigue! The first Hollywood mention of global warming, all the way back in the early 70s. What is Soylent Green made of?? Doublebill it with Rollerball??
An Inconvenient Truth (2006) – Al Gore’s powerpoint presentation, ’nuff said.
The Day After Tomorrow (2004) – schlockorama!!
Mindwalk (1990) – maybe a bit hard to get, and a bit of a chin-stroker, but excellent on paradigm shifts and the like. Liv Ullman and a couple of jobbing American actors wantering around Mont St Michel talking about particle physics. Book cinema one for this one…
To be avoided: Just Do It, The Age of Stupid.
