This early sci-fi masterwork by Herbert George Wells with music by Arthur Bliss is a powerful piece of film-making. Adapted from Wells' somewhat different work by the author, it presents a look at the human future with the subject of periods of war as versus periods of 'peace'. The structure is that after a contrasted-pair of episodes of normalcy and gathering clouds of war, the script allows the war to happen. Two families, the Cabells and the Passworthys disagree about what may happen; Passworthy takes a hopeful view of civilization's "automatic" progress; Cabell is the thinker, the doubter. Their city Everytown--obviously London-- becomes wrecked by a war featuring tanks, a magnificent war march by Bliss, and the end of civilization. The second portion finds people living in the wreckage of what had been the city under a "Boss", played with bravura by Ralph Richardson, whose woman, lovely Margaretta Scott, is as fascinating a dreamer as he is a concrete-bound dictator type. He is trying to rebuild old WWI airplanes so he can attack a nearby hill tribe to complete his petty kingdom; a young scientist complains about having his work continually interrupted demands for planes--etc.--everlastingly; this is Wells' comment on war versus progress. The survivors are subject to a plague called "The Wandering Sickness" also. Enter a modern flying machine piloted by the Cabell of the first section of the film, now part of Wings Over the World, an International Scientists' Coalition, who are planning to end warfare forever. This flight-suited modernist has fascinating conversations with the Boss and his woman, their attraction being evident; then Boss sends up his aircraft against them, the Scientists come with huge numbers of planes and drop the "Gas of Peace" onto the ruins of Everytown. Only the Boss dies, fighting too hard against the pacifying. The film then shows ore being mined and by slow steps being made into the girders of a magnificent new futuristic city of towers. In section three, a future Cabell argues with a future Passworthy over the morality of human science. Passworthy wonders if they have a right to send men to the Moon; Cabell champions man's right to advancement and the need to expand his horizons. The son of Passworthy and Cabell's daughter, are the astronauts being sent. Theotocopulos, a religious-minded Luddite, makes a fiery speech on a huge screen in the city's Forum and leads an attack on the 'space gun' that is to fire the new rocket free of Earth's gravity. The climax of the plot is the firing of the space gun successfully; the denouement and ending is a speech by Cabell praising worth and science that is universally considered to be the most profound defense of the mind ever penned. "It is all the universe--or nothing!" Cabell tells Passworthy. "Which shall it be?" As Cabell, Raymond Massey gives perhaps his greatest screen performance; he is thoughtful, compassionate, and reasonable, a true scientist. As the rabble-rouser who wants to end the Age of Science, Cedric Hardwicke is perfect and powerful. Edward Chapman playing Passworthy does admirably impersonating the voice of convention and fear. The storyline is logical, frequently beautiful and always interesting. Given the near-extinction of mankind, the idea of a civilization run by rebuilder scientists is rendered plausible and credible to the viewer. This is a triumph for the director, William Cameron Menzies, for Bliss and for all concerned. Listen to the dialogue with someone you love; within its constructed limits, this is a thinking man's drama debating two possible human futures--progress or its reactionary opposite.

As a horror-movie fan I try to watch all significant novelties of this genre, especially those which are the products of my native cinema. And I can say that that the "Power of Fear" (or "Vedma" as the Russian title of it) is one of the weakest film among them. Firstly, it can't scary even a little kid, it paces so slowly and so predictable that there is no place for the real horror. Frankly speaking, it's bad in all points: from the goofy plot (I don't know why the Russian producers/director decided to transform the classic story about Ukrainian witchcraft into some lame and ridiculous modern-day-America thriller. I absolutely agree with the previous reviewer  it doesn't thrill a bit) and to the terrible and cheesy actors' work. All actors including the leading Valeri Nikolayev and Yevgeniya Kryukova who are quite famous in Russia look like wooden dolls or something like that and it seems to me they didn't even bother to play at all, only spoke their English lines without any expression. And at the end I don't really understand why they filmed this flick in English with Russian actors? I think it was their wrong turn. At least they could cast some American or English actors for the leading parts to make them look more convincing. The same I can say about so called "small American town backgrounds" which were shot in Estonia and look like it. The only positive moment I found in the "Power of Fear" is the visual effects. They are not excellent but rather good for the Russian film. And the music is OK, at least it doesn't irritate me. That's why I give it two stars. Overall, if you want to see good horror film  don't waste your time and money on this boring flick. And if you are looking for something that claims to be a Russian horror I'd advise you to find a copy of "Viy or The Spirit of Evil". It's really the terrific movie based on the same novel as "Power of Fear" but much, much better.
