It's a Wonderful Life (1947)

It’s Christmas, snow is falling, and James Stewart’s protagonist is contemplating suicide, driven to despair by financial misfortune. Those who know director Frank Capra’s film only by its reputation as a sentimental seasonal favourite are often taken aback by how unflinchingly it shows ever-amiable Stewart’s kindly local banker brought low by the machinations of a cruel world. True, the story involves a certain angelic intervention to show him that his travails have all been worthwhile, yet it’s only because this modern parable plumbs the depths so vividly that its vision of redemption proves so persuasive. Its enduring popularity may indeed derive from Capra’s insistence that friendship matters more than material gain, a telling message of solace in a secular capitalist society.
