Factual error: Late in the big chase scene, Sol climbs on top of the Bentley just as Sinclair decides to drive it straight through a bus that is blocking the highway. Somehow, the Bentley levitates from the highway to about 4 or 5 feet in the air, penetrating the bus passenger cabin rather than impacting the chassis of the bus. Also, as the bus inexplicably explodes in a fireball, Sol (who was atop the car) is torn to pieces, with his decapitated head hurtling straight into the camera. Without lungs or diaphragm, Sol's head is still audibly screaming.
Factual error: The bar shown in Iqualuit is not real. Iqualuit only has 6100 or so people, and there is no bar like the one shown in the movie. The building is wrong - it doesn't even look like any buildings in Iqualuit. There is one bar that looks nothing like the movie, one Legion, and a bar in the hotel in Iqualuit.
Factual error: In the streetcar scene a passenger is a soldier wearing a US Army green uniform with a CIB, Comat Infantry Badge. At the time US uniforms were brown and there is no plausible reason for this US soldier to be in that country.
