I had watched this as a kid on a now-defunct Sicilian TV channel, but it seems to have vanished off the face of the Earth in the interim – that is, until the recent DVD release from Universal as part of their second "Sci-Fi Collection". The film was yet another infrequent genre entry from Paramount – after 1931's DR. JEKYLL AND MR. HYDE and the trio from 1933 ISLAND OF LOST SOULS, MURDERS IN THE ZOO and SUPERNATURAL; interestingly, it was a Technicolor production – the first to be shot in this process after Warners' two earlier experiments DOCTOR X (1932) and MYSTERY OF THE WAX MUSEUM (1933). Plot-wise, DR. CYCLOPS was a variation on the "shrinking" theme explored in MGM's THE DEVIL-DOLL (1936) – which proved quite popular over the years, as can be attested by the likes of THE INCREDIBLE SHRINKING MAN (1957), ATTACK OF THE PUPPET PEOPLE (1958), CURSE OF THE DOLL PEOPLE (1961), etc. The titular character – for which underrated character actor Albert Dekker is probably best-remembered and his most notable genre contribution alongside the dual role in AMONG THE LIVING (1941) – would, of course, fit in with the era's virtually interminable parade of mad scientists; though, typically, he means well by his experiments, his approach to science (and his fellow man) is utterly ruthless. Working in seclusion but deterred by his failing sight, he invites three eminent colleagues to confirm his findings without actually divulging the nature of his experiments; when they begin to get curious and decide to stick around, he does not shrink {sic} at the prospect of using them for guinea pigs! Soon enough, they are fighting for their lives – and not just from the wily doctor, as everyday objects become inaccessible (a door-knob) or otherwise take menacing proportions (a cat)!; on the other hand, they take advantage both of their current dimension (hiding in places where Dekker cannot get at them) and the doctor's own physical drawback (breaking the spare sets of lenses, kept handy in a drawer, while he is sleeping). Interestingly, the shrinking process eventually halts and the subjects start reverting to normal size – which is how the heroes, having gotten rid of "Cyclops" in the very well where he stores his all-important ray-gun, are able to return to civilization after several months of 'convalescence'. The handsome-looking film, an entertaining and efficient 76 minutes, makes for a worthy addition to director Schoedsack's genre resume' (which includes seminal titles like THE MOST DANGEROUS GAME {1932} and KING KONG {1933}, notable ones like SHE {1935} and MIGHTY JOE YOUNG {1949}, not to mention the lesser but endearing SON OF KONG {1933}).

"Dr. Cyclops" was an unusual horror film for its time. It did not use any major stars and was shot in glorious technicolor (unheard of for a film of this type). The plot is a typical "B" movie plot but the special effects and the color photography are what really sets this film apart.

The story involves "Mad Scientist" Dr. Thorkel (Albert Dekker) who summons three scientists (Thomas Coley, Janice Logan, Charles Halton) to his remote South American laboratory to seek their advice on his secret project. Along the way they are forced to bring muleskinner (Victor Kilian) along.

It turns out that the evil doctor has discovered the secret of miniaturization. To prevent them from cashing in on his discovery Thorkel shrinks the three scientists, the muleskinner and nosey local Pedro (Frank Yaconelli) to miniscule size. The rest of the film chronicles their efforts to escape.

The real star of the film are its special effects. Accomplished through a combination of split-screen, rear projection, miniatures and over sized props, the effects are quite convincing for the time. One shot I thought was quite well done was a scene where the evil doctor picks up one of his victims in his hand.

Because most of the budget was spent on color and effects, the quality of the acting suffers. Dekker does OK as the title character (a name given him by his victims because of his failing eyesight). The others are just barely adequate. Veteran Paul Fix, who could have raised the acting up a level, appeared briefly in the opening reel as Thorkel's sceptical assistant.

Partially sighted molecular biologist Dr. Alexander Thorkel (Albert Dekker) invites a team of fellow scientists to help him with his work at his laboratory deep in the Amazon jungle; within hours of their arrival, the problem that Thorkel has been struggling with has been resolved, and the surprised boffins are immediately given their marching orders, none the wiser about the precise nature of their ungrateful host's experiments.

Eager to learn more, the curious group sneaks into Thorkel's room to take a peek at his notes, but discover more than they bargained for when they become the guinea pigs in the secretive genius's next experiment: bundled into a room, they are exposed to a heavy dose of radiation that reduces them to a fraction of their original size.

Directed by Ernest B. Schoedsack, one of the team responsible for bringing King Kong to the screen in 1933, Dr. Cyclops is a fairly routine mad-scientist sci-fi/horror potboiler, but one that benefits immensely from a incredible array of groundbreaking special effects and sumptuous Technicolor photography. Technically, this film is way ahead of its time, looking more like a product of the mid 1950s than the early 40s, and for this reason alone it should be a priority for all fans of fantastic cinema.

Utilising a combination of careful camera placement (low shots to make Thorkel appear huge; high shots to make his victims appear small), detailed over-sized sets and props, rear projection, split screen and mattes, Schoedsack and his effects team create scene after scene of memorable movie magic. Take into account that this movie is now over 70 years old and it cannot fail to impress.

On the downside, the score is extremely heavy handed and some of the performances are less than stellar (Dekker is excellent, but the exaggerated mannerisms adopted by the pint-sized profs are embarrassingly trite). Thankfully, these are minor quibbles when measured against the film's massive technical accomplishments and the film remains a consistently entertaining experience nonetheless.

7.5 out 10, rounded up to 8 for the sight of yummy egghead Dr. Mary Robinson (Janice Logan) in her sexy makeshift toga: she might be reduced to a foot in height, but she's certainly no shrinking violet.
