Burt is diagnosed with an eye infection caused by exposure to a graboid. At first, his eye is bloody, when they take a sample. The blood goes from being in his eye, around his eye, to completely gone within just a few minutes.
The digital clock above the medical area door is inconsistent. This includes a part where the clock shows a time of approximately 6:30 PM when the characters go outside for a few minutes to help Dr. Freezze, and when they come back inside it is around 9:15 AM.
When the aircraft they use to fly over Alaska is shown first, it has big, soft bushwheels. When it lands on a dirt road, it has small standard wheels.
The opening scene is set in ''Nanavut Province - Canada / 60th Parallel", but the correct spelling is "Nunavut", it's a Territory, and its southern border (with the Province of Manitoba) is at 60°N.
Arthroscopic surgery is performed on a joint, not on the intestines to remove a tapeworm as Valerie tells Hummer in the hospital. She could have meant "endoscopic surgery" which is performed using a scope, a flexible tube with a camera and light at the tip.
Valerie goes to Oregon State and wears both a cap and shirt with the school's mascot but there is a University of Oregon flag flying atop the main building.
When Valerie is on the phone with Burt she says "You've hunted and killed them on two different continents, Mr. Gummer." He has actually hunted and killed them on three: North America (Nevada & Mexico), South America (Argentina), and Africa (South Africa).
When Dr. Ferezze has just been eaten, Valerie notes that the creatures have recently emerged from hibernation, and that based on their body mass index of the creatures, they need to eat a lot.
BMI is a measure developed to estimate human body proportions and nutrition status. It is a completely meaningless measure for a graboid.

At the supposed Arctic research base there is a simple glass door to the patio at the main compound. Hardly enough insulation against the cold, during winter.
While this is suppose to be based in the Canadian Arctic it is clear that the location is based in the white dunes of Cape Town. The snow clearly acts like sand and not snow.
On the first overhead of the aircraft initially flying towards the base there are cross braces on the windshield, suggesting it is a Piper Cub. The interior shots and subsequent exterior close-ups show a windshield with no cross bracing, suggesting it is a Cessna 170.
They are in the Canadian arctic but have giant picture windows on every wall. no building in the arctic would have those. the building would be freezing all the time.
The setting is northern Canada but the vehicles are right-hand drive due to the filming location being in South Africa.
The Piper PA-22-150 has registration number ZU-BKC which is for South Africa. Canadian registration numbers begin with the letter C (eg C-BKC).
