Neat early special effects in Technicolor
“Doctor Cyclops,” a 1940 science fiction film that uses shrunken people as its centerpiece, was the first genre picture shot in 3-strip Technicolor. “Mystery of the Wax Museum” and “Dr. X” had been photographed in the earlier 2-strip Technicolor process eight years earlier. Directed by Ernest B. Schoedsack, who co-directed 1933’s “King Kong,” “Doctor Cyclops” falls into the mad scientist sub-genre.<br /><br />Like “Kong,” “Doctor Cyclops” involves a journey into the jungle. A group of scientists venture thousands of miles to find out what reclusive Dr. Thorkel (Albert Dekker) is up to. We learn he’s been experimenting with a radioactive ore that requires him to wear a heavy, cumbersome suit. The group, headed by Dr. Bulfinch (Charles Halton), includes mineralogist Bill Stockton (Thomas Coley), biologist Dr. Mary Robinson (Janice Logan), and Steve Baker (Victor Kilian), who owns the mules needed to get through the jungle and suspects Thorkel may have found a rich mine.<br /><br />Thorkel has summoned the scientists to examine a significant finding because his eyesight is too poor for him to be certain of what he has seen through the microscope. The moment he has their corroboration, he asks them to leave. Incensed at Thorkel’s brusque rudeness, Bulfinch and the others set up camp and start poking around.<br /><br />Thorkel finds and imprisons them along with his own assistant, Pedro (Frank Taconelli), turns his invention on them—a radioactive ray that reduces them to 12 inches in height. The rest of the film revolves around how the shrunken folks use their ingenuity to try to outsmart and escape from their giant nemesis. One of their ploys is to break his thick glasses, but they succeed in breaking only one lens. That Thorkel can now see only with one eye gives the movie its title.<br /><br />Within the first couple of minutes, a character tells Thorkel “You are tampering with powers reserved for God,” a phrase spoken endlessly in mad-scientist pictures. The script draws upon earlier films, such as “The Most Dangerous Game” and is a forerunner of 1957’s “Incredible Shrinking Man.” Featuring a range of special effects such as rear projection, mattes, oversize props, and combining live actors with filmed backgrounds, “Doctor Cyclops” manages to create the illusion that the human prisoners are smaller than a dog and a well-fed cat is their adversary. Director Schoedsack allows these effects to take center stage over the weak story and poor dialogue.<br /><br />Dekker embraces the role of Thorkel. Tall himself at 6 foot two and bald, he is reminiscent of Peter Lorre’s Dr. Gogol in “Mad Love.” Though he’s pretty careless about securing the shrunken visitors (he takes a lot of naps), this gives the special effects department a chance to shine as the small people try to escape. When he’s awake, Thorkel torments and taunts them. Dr. Bulfinch appears to be a particular target of Thorkel’s venom. In one beautifully crafted scene, Thorkel, holding a butterfly net, appears on a process screen behind Bulfinch. As he reaches to the left, a huge butterfly net in front of the screen moves in from the left toward Bulfinch and comes down on him as Thorkel gestures downward. The blend of live and filmed action is perfect.<br /><br />Comparisons with “King Kong” are inevitable, since Schoedsack directed both pictures. “Doctor Cyclops” is well made but lacks the emotional impact of “Kong” and its exciting stop-motion scenes. “Cyclops” never explains why Thorkel is experimenting with miniaturization. Apart from Dekker, the cast is comprised of bland unknowns. A number of decisions they make in trying to outsmart their captor don’t make sense, and we never see how they regain their normal size. It’s Dekker’s show all the way as his character erases a fine line between the dedicated scientist on the verge of an amazing discovery and a crazed narcissist with a God complex.<br /><br />Bonus features on the Blu-ray release include an audio commentary, “Trailers From Hell” with Jesus Trevino, and 4 theatrical trailers.

Here is a brief synopsis of the title : From Ernest B. Schoedsack and Merian C. Cooper, the legendary team behind King Kong, The Most Dangerous Game and Mighty Joe Young, comes this early Technicolor science-fiction classic about a brilliant but deranged physicist who learns how to shrink his enemies to one-fifth their normal size! Four explorers are summoned to the remote jungle laboratory of the legendary scientist Dr. Thorkel (Albert Dekker, Kiss Me Deadly, The Killers, Beau Geste). When they arrive, they discover that his brilliant mind has been warped by radiation and decide to return him to civilization for help. But the half-blind, half-mad Dr. Cyclops will have none of that and uses his experimental body-shrinking device to stop them. Now, harmless items and small creatures suddenly become giant-sized instruments of death! The impressive use of landmark special effects, which garnered an Oscar nomination (Best Effects, Special Effects), helped make this sci-fi yarn one of the most imaginative and memorable horror-fantasy films of all time.Special Features:-Brand New 4K Master -NEW Audio Commentary by Film Historian Richard Harland Smith -Trailers From Hell with Jesús Treviño " -Dual-Layered BD50 Disc -Optional English Subtitles -Theatrical Trailer.
