Monster Mayhem

There comes a point in every mad scientist's career when somebody really needs to grab him by the shoulders and say, "Maybe don't touch the glowing meteorite." Unfortunately for Dr. Janos Rukh, nobody gets there in time.

Watching The Invisible Ray in 2026 as the next chapter of Karloff and Lugosi's Tales of Gothic Terror – Part One in Umbrella Entertainment's Universal Horror: Monsters and Curiosities (1923–1960) collection is a wonderful reminder that Universal didn't need Frankenstein's laboratory to get completely fucking nuts with science. Here we get cosmic rays, ancient meteorites, radiation poisoning, glowing human beings, instant death by touch, miraculous medical cures, jealousy, revenge, and Boris Karloff slowly going batshit while Bela Lugosi—the same Bela Lugosi who was gleefully torturing people in The Raven—somehow emerges as the reasonable scientist. What a difference a year makes. Directed by Lambert Hillyer and released in January 1936, this thing is science fiction wearing Universal Horror's favorite black coat, and I love the strange little bastard for it.

Karloff is Dr. Janos Rukh, a brilliant scientist who has developed a device capable of capturing light from the Andromeda galaxy and using it to essentially watch Earth's ancient past. That's already enough movie for me, but The Invisible Ray has barely cleared its throat. Rukh discovers that a massive meteorite crashed into Africa thousands of years earlier and leads an expedition to recover it, accompanied by fellow scientist Dr. Felix Benet (Lugosi), Rukh's wife Diana (Frances Drake), and others. Rukh finds the meteorite and discovers Radium X, an element possessing extraordinary powers. Then he gets exposed to it. Suddenly the man glows in the dark and his touch kills instantly. Benet develops an antidote capable of keeping the poisoning under control, but there is a catch because there is always a catch in a Universal laboratory: Rukh's mind begins slipping right along with his humanity.

This is Karloff's show, and what I love about his performance is how little it resembles Frankenstein's Monster. Rukh begins as arrogant, certainly, but he's not some cackling lunatic waiting for an excuse to start killing people. He's a man who believes he's touched something bigger than himself, only to watch other scientists turn his discovery into something capable of healing people while his marriage falls apart around him. Jealousy starts eating whatever the radiation hasn't already poisoned. Karloff lets that resentment simmer rather than explode immediately, and when Rukh finally crosses the line into revenge, there's still enough wounded humanity left behind those eyes to make the whole thing tragic. And Lugosi? He's restrained. Intelligent. Rational. Hell, he's practically the adult in the room. Dr. Benet uses Radium X to restore sight to the blind, giving Lugosi the rare opportunity to play a scientist whose response to an incredible discovery isn't "Excellent! Now where did I put the torture equipment?" Seeing Karloff become the unstable menace while Lugosi tries to save lives is one of the movie's great pleasures.

And then there's the glorious pulp insanity surrounding them. Rukh glows. His fingerprints leave lethal evidence behind. His mother can recognize him despite his increasingly monstrous transformation. Franz Waxman's music occasionally carries echoes of Bride of Frankenstein, while Universal's familiar machinery hums and sparks around another scientist who absolutely should know when to quit. Even some of the sets were being shared with Flash Gordon, which somehow makes the whole production feel even more like Universal dumped its horror and science-fiction departments into the same laboratory and flipped the switch. Yet beneath all that wonderful 1930s pseudoscience is an idea that still works: discovery doesn't automatically make us wiser. Rukh finds something capable of changing humanity and immediately begins treating it as his. His discovery. His glory. His legacy. When the world refuses to behave accordingly, genius curdles into obsession. The radiation might be killing him, but ego gets there first.

That's why The Invisible Ray holds up so well in 2026. It's not The Black Cat, and it doesn't have the wonderfully sadistic lunacy of The Raven, but it isn't trying to repeat either film. It's a cosmic science-fiction tragedy with horror crawling around underneath, powered by another terrific Karloff performance and one of Lugosi's most refreshingly unusual roles. Lambert Hillyer keeps things moving, George Robinson's photography gives the increasingly bizarre story plenty of atmosphere, and the Radium X effects still possess that handmade Universal magic that no amount of digital perfection can replace. As another Karloff/Lugosi pairing, it's fascinating precisely because the movie rearranges the pieces. This time Karloff gets the madness. Lugosi gets the cure. And science, once again, gets everybody into a shitload of trouble.

The Invisible Ray is one of those Universal pictures that deserves to be dragged out from behind the bigger monsters and allowed to glow a little on its own. Karloff is terrific as a scientist whose greatest discovery becomes his death sentence, Lugosi is surprisingly effective as the voice of reason, and the movie's collision of cosmic science fiction, Gothic horror, revenge thriller, and wonderfully impossible 1930s science makes it enormously entertaining. As part of Umbrella Entertainment's Universal Horror: Monsters and Curiosities, it also demonstrates exactly why a collection like this matters. We already know the monsters. These are the movies lurking behind them. And sometimes the curiosities are every bit as much fun.

Video

Umbrella Entertainment's high-definition presentation gives The Invisible Ray plenty of opportunity to show off George Robinson's atmospheric black-and-white photography, from Rukh's wonderfully overstuffed laboratory to the African expedition and increasingly shadowy final act. The machinery, electrical effects, facial textures, and especially Rukh's radioactive transformation benefit from the added clarity without making the picture look scrubbed of its age.

Grain remains part of the image, contrast is suitably strong, and the glowing Radium X effects retain their wonderfully unnatural appearance. This isn't a movie that should look slick. It should look like somebody found something in a laboratory that absolutely should have remained buried.

Audio

The audio presentation keeps the dialogue clear while giving Franz Waxman's score and Universal's collection of humming, buzzing, sparking laboratory equipment appropriate presence. Karloff's increasingly fractured performance benefits enormously from a clean presentation, especially as Rukh moves from scientific certainty toward paranoia, while Lugosi's quieter delivery remains equally intelligible.

There's no attempt to make an eighty-year-old mono soundtrack pretend it's something modern, and there shouldn't be. The presentation preserves the character of the original mix while allowing the film's wonderfully pulpy atmosphere to come through cleanly.

Supplements:

While short on extras, the commentary is just a plethora of film history talking about everything from Whale to the actors to Pre-Code history and much more. It more than compliments the film well.

Special Features:

Within Karloff and Lugosi's Tales of Gothic Terror – Part One, The Invisible Ray is exactly the sort of movie that makes Umbrella Entertainment's Universal Horror: Monsters and Curiosities (1923–1960) collection such a goddamn treasure chest. Following Murders in the Rue Morgue, The Black Cat, and The Raven, we're now watching Universal actively refuse to give Karloff and Lugosi the same parts twice, turning their fourth major pairing into cosmic science fiction rather than another Gothic chamber piece.

The collection's hardcover companion book and broader historical presentation only deepen that appreciation, but the real special feature is having these movies together in sequence. Watch them this way and you can see Universal experimenting in real time—moving the furniture around, swapping hero and villain roles, mixing genres, and discovering just how much mileage they could get from putting Karloff and Lugosi in the same damn room.
