Anyone checked that trailer? Looks pretty quirky. The bloke shooting at the comet with his hand gun at night in his backyard yelling "you're not taking me alive!" cracked me up.
The movie is an attempt to highlight climate change by analogy, i.e. a definite planet killer appears in the sky, but the president, media and business are not concerned and decide to wait and see, meanwhile big business learns it is full of valuable minerals and wants to make money...
