H.G. Wells' remarkable popularity shows no signs of diminishing nearly 70 years after his death. It's nowhere more apparent than in Hollywood, which continues to churn out adaptations of  the science-fiction pioneer's output, which includes The Time Machine (1895), The Island of Doctor Moreau (1896), The Invisible Man (1897), and The War of the Worlds (1898).

Yet Wells' later, politically charged work is virtually ignored today. A committed socialist, he wrote passionately in the 1920s and '30s about the dangers of extreme nationalism, and called instead for a united world government organized around Marxist ideals.

Wells' utopian vision of a socialist future is hardly persuasive today, but it fueled one of the more unique science-fiction films produced during his lifetime, William Cameron Menzies' 1936 epic Things to Come, which Wells wrote. A newly restored edition of the film is now available from the Criterion Collection.

Adapted by the novelist from his polemical (even baldly propagandist) 1933 work, The Shape of Things to Come, and featuring a stellar cast, including Raymond Massey and Ralph Richardson, the film is a historical chronicle of humanity's progress from 1940 to 2036. Made on the eve of a cataclysmic battle, it opens with a savage war that goes on for decades. The killing ends only when a daring visionary unites humanity through the power of rationality, science, and technological progress. (www.criterion.com; $29.95 DVD; $39.95 Blu-ray; not rated)
