We've successfully heeded that message for more than half-a-century since On the Beach, and for all our sakes, I hope we continue to do so.
But On the Beach should be required viewing for every politician who takes an oath of office, the globe around, just to be certain. Especially those who strut across the stage, cocksure in their macho posture about destroying our enemies.
The world isn't that simple, as On the Beach suggests. Our sons and daughters shouldn't pay the price for some congressman's simple-minded reliance on force.
As On the Beach reaches its solemn, inescapable conclusion, all the film's main characters must determine how they wish to face their imminent demise. Peter, Mary and Jenny remain a family to the end, before taking the suicide pills. Though increasingly in love with Moira, Dwight decides to return to America with his ship and crew...so they can die at home. And old Julian, who has re-fitted a Ferrari and won the Grand Prix, chooses his own way of leaving this Earth as well: carbon monoxide poisoning.
The final shots of the film provide us glimpses of an eerily empty Melbourne -- rendered eternally silent and lonely -- by the end of all human life on the planet.
