"The Deadly Invention" showcases Zemans unique approach to movie-making and aesthetics, sometimes maybe in a too strict manner. To keep the mix of animation, stop-motion and real-life actors / sets manageable, the movie is done in black and white - which makes it more similar to the 19th century steel engravings accompanying Verne editions, but loses some atmosphere. I don't know why the whole movie is kept in neutral grey; even early filmmakers coloured their B/W films from scene to scene according to the story to enhance the experience. Seems like an oversight to me.As mentioned in the title, this is required viewing for animation addicts; for pure enjoyment I'd recommend Zeman's later stuff, like "The Stolen Airship" which came nearly 10 years later and has colours (handcrafted, of course) as well a a more easygoing flow of story.

Few films have ever captured the feel of a fantasy world better than this one. The opening sequence alone (no, I'm not talking about the Hugh Downes intro) is absolutely masterful, presenting us with a seemingly unending series of striking images done using a technique (described at length by other reviewers) I don't think has ever been used again in a feature. Fantastic planes, trains, and airships soar past evoking a sort of "steam-punk" atmosphere of retro technology before that term was ever coined. Film fans, Verne fans, fans of pure hand-crafted cinema artistry and imagination must do themselves a favor and check this movie out.

I first saw this film I think about 1963 as a 12 year old on KHJ TV in Los Angeles and was totally hooked on it. years later I realized that it was pretty much based on a combination of Verne tales....The Czech title being "A Dangerous Weapon"....I love it!I was a graduate of Occidental College in LA...Terry Gilliam proceeded me by some 12 years......Why do I comment on this? - Well, if you watch this film it has Gilliam's shtick written all over it....I only wish I'd had the chance to question him at the college bicentennial in 1986.....I have little doubt that he'd deny that Zeman's films had had any influence on him, but it's a obvious as the nose on your face! Anyone notice that? I love the Professor Serke, the Count's number one quiz kid. If I didn't know better, I'd swear that he was a character right out of the much later "Wild Wild West"...Couldn't you see him as yet another evil genius out to take over the world?. Victorian gadgets galore!This film makes me feel as thought I'm part of that era, it makes all of it seem so alive!Oh yeah, the film would not have had nearly the impact that it's had on me were if not for Lisko's fabulous musical score...It emotes the charm of the Victorian era in a manner I've not seen before or since. It's also interesting that his music has certain synthesizer-Esq qualities as used for sound effects.Has anyone ever noticed the obvious similarities in the small reconnaissance submarine to Professor Fates' craft in the much later "The Great Race"?.......I doubt it! Captain Spade........Were he and Bluto twin brothers separated at birth?

***Spoilers ahead*** My late childhood had two cinematographic icons: Star Wars and this film by Czech genius Karel Zeman. A Jules Verne encyclopedia where XIX century illustrations come to life in exquisite black and white photography, combined with stop motion and conventional animation. Verne's spirit of adventure is fully present throughout the film, as well as a very modern questioning on the moral limits of power and advanced technology. In fact, it brings atomic energy into Verne's universe in a very elliptic and elegant way. Also elliptic and elegant is the demise of the villain, with a (probably nuclear) explosion sending his hat flying over the sea. The resolution of the film is symbolic and very satisfactory, something very rare today, when a lot of films don't seem to know how to end themselves.I was fortunate to catch this gem in reruns on local TV in the late 70s: it enhanced my enjoyment of Verne's fiction and of cinema.10 out of 10 for Karel Zeman, under-appreciated master of imagination.
