The movie resembles "Dr. Strangelove," an all-star cast in a dark comedy featuring a somewhat implausible scenario that is a metaphor for a serious real world threat. Dr. Strangelove dealt with a rogue general triggering a nuclear exchange, but the real world concern was nuclear war generally. "Don't Look Up" is ostensibly about the threat of a comet hitting the earth but it is really a stand in for the threat of climate change. I'm not sure dark comedies end up sufficiently conveying the concern of the movies' writers and producers, but here is hoping.
