At 7 degrees where I live at the time I write this at the end of November, along with heavy snowfall in places like Chicago and Detroit, I’m willing to declare it the first gosh darn week of winter. Yeah, I’d rather just say it that way than have it bleeped. And yeah, it’s not actually the first week of winter (that won’t happen until December 21st) but you know where I’m going with this. While the holiday season is creeping up fast with all that it entails, there are other movies to enjoy besides just Christmas horror. Stuff like 30 Days of Night, The Shining, and today’s subject, The Thing, are all great watches for the snowy season.

The Thing happens to be my favorite of these, and my favorite horror movie of all time. I’d wager it’s near the top of a lot of your lists too. There are plenty of reasons why, but today I want to focus on one specific scene that really combines everything that makes the movie great. Get your scalpels and torches ready…. we’re diving into the blood test scene.

Origins of The Thing

The Thing has its origins in a couple of places. First, there’s the 1951 classic The Thing from Another World, directed by Christian Nyby and presented by Howard Hawks. This matters because it was the first film adaptation of the source material and because Hawks was one of John Carpenter’s favorite filmmakers.

Similarly to how The Nightmare Before Christmas is often mistakenly credited to Tim Burton instead of Henry Selick (and yes, I had to look that up instead of pulling it off the top of my head), The Thing from Another World is often thought of as a Howard Hawks film. It’s not, but it feels like one, and he had his hands all over it.

That’s important because when Universal went looking for properties to remake, The Thing from Another World shot right to the top of the list. While The Texas Chain Saw Massacre director Tobe Hooper was nearly in the director’s chair, the project ultimately landed with John Carpenter, which was basically kismet, given his admiration for Hawks.

The Original Story: Who Goes There?

The real source material is Who Goes There?, written by John W. Campbell during the golden age of science fiction. Originally published in 1938, it was later expanded with additional chapters. Even later, discovered manuscripts allowed the story to grow into a fuller version, eventually published as Frozen Hell. The author originally envisioned a full novel, possibly titled Pandora, referencing Pandora’s Box.

As for The Thing itself? You know how that went. Critics absolutely hated it. It wasn’t quite the bomb people make it out to be, bringing in nearly $20 million on a $15 million budget, but that wasn’t what Universal or Carpenter were hoping for.

Fast forward a few years, though, and it’s no longer just a cult classic. It’s firmly in the conversation for greatest horror film of all time.

What Makes The Thing So Great

The Thing built its reputation on a few key elements:

1. The Acting

Led by Kurt Russell, the film features incredible performances across the board, from Wilford Brimley to Keith David to Richard Masur.

2. The Effects

The practical effects are still unbelievable. From the dog kennel sequence to the infamous defibrillator scene (where we are indeed not effing kidding you), it’s a full showcase of horror craftsmanship.

3. The Paranoia

This is the big one. The paranoia runs through the entire film, from the moment they question why a dog is being chased, all the way to the end. It’s the crux of the movie.

Setting Up the Blood Test Scene

By the time we reach the blood test scene, the group has been whittled down to:

MacReady

Palmer

Childs

Nauls

Garry

Windows

Blair is locked away, and, based on that noose in the background, we’re pretty sure he wasn’t planning on sticking around much longer.

Earlier, the group realized a blood test might reveal who’s human and who’s an imitation. But that plan fell apart when the blood supply was sabotaged. Now, they’re going with a much more primitive, but effective, solution.

The Scene Begins

After Norris suffers a heart attack and reveals himself as a Thing (including the head-that-sprouts-legs moment), MacReady gets an idea. At around the 1:18 mark, he starts tying everyone up.

Garry suggests rushing him. Childs refuses. Clark tries anyway… and gets shot between the eyes.

That moment alone proves MacReady isn’t messing around.

Building Tension

This is where the scene becomes something special. Mac explains the test while staring down a group of men he doesn’t trust… and neither do we.

He draws blood from each of them, places it in petri dishes, and heats a wire with a flamethrower. No theatrics. Just enough heat. The idea: every piece of the Thing is alive. If you attack it, it will react.

The First Test: Windows

Windows goes first. And the tension is unbearable. There’s about 40 seconds between placing the sample down and applying the hot wire, and it feels like forever.

Everyone’s faces tell a story:

Palmer and Garry: confusion and concern

Windows: anger mixed with fear

MacReady: pure focus

When nothing happens, the relief is real, for both Windows and us.

MacReady Tests Himself

Next, MacReady tests his own blood. No buildup. No suspense.

We assume he’s human, but Childs doesn’t care. To him, the test means nothing.

The Fake-Out

Then come the dead bodies. Everyone expects Clark to react. He doesn’t.

Now the doubt creeps in. Is the test even real? Did MacReady just kill an innocent man?

The Genius Detail You Probably Missed

At around 1:22, there’s a subtle switch. The hand holding the blood dish? It’s no longer Kurt Russell’s; it’s a prop made by Rob Bottin’s effects team. An imitation… holding a test meant to detect imitations. And almost no one notices.

The Explosion

Then comes Palmer. There’s arguing. Doubt. Accusations. And right before the reveal, MacReady flinches ever so slightly. He knows what’s coming.

The blood erupts.

It’s one of the greatest jump scares ever, and it always works.

Chaos Unleashed

Everything falls apart instantly. Palmer transforms. Windows gets caught in the chaos. Flamethrowers fail. Men panic.

Palmer is eventually burned and blown apart, but not before taking Windows with him.

The test works. But it costs them.

The Aftermath

After that, no one questions the test anymore.

Nauls: human.
Childs: still defiant.
Garry: revealed human while staring down two flamethrowers.

And then, finally, a release. Garry drops a perfectly timed line about not wanting to spend the rest of the winter tied to the couch. It’s funny. It’s human. And it cuts through the tension.

Why This Scene Still Matters

Everything leading up to this scene works. Everything after it works. But this is the peak. It even improves on the novella.

The blood test scene has been copied, most notably in The Faculty, and poorly imitated in The Thing prequel. But nothing touches the original. It’s a scene that never gets old in a movie that never feels stale.

And it’s absolutely worthy of study.… but that’s me telling you something you already knew. After all, you were the only one who could have gotten to that blood.
