I couldn't see that in the movie. But then I'm probably reading into it what I know opposed to what the sleeping masses believe.There's some cosmic irony that they chose the comet theme as their metaphore, if the goal is to promote global warming propaganda as the take home message from the movie.
My feeling was that it is supposed to work on several levels including the information about the possibility of a 'big one'. Isn't this the time when the veil begins to lift and tptb must balance their act with occasional truth and concessions however wrapped?
