Factual error: The Royal Canadian Mounted Police are shown checking baggage in the final scenes at the same time that FBI agents are making arrests. The flight landed in Goose Bay, Newfoundland and Labrador, Canada. According to the Criminal Code of Canada, any crime committed during an international flight that ends on Canadian soil is deemed to have been committed in Canada. That being the case, the RCMP as the national police force has full jurisdiction. There is no way the FBI would be involved at that point.
Factual error: When looking at Anna's cell phone, you can see the logo for Telus, a Canadian communication company that only offers cell phone service in Canada.
Factual error: In the scene in which the scientists observe the emergence of the black hole out in the Lechuguilla desert, as it pokes out of the ground unexpectedly near to their base everything in the tent is shown powerfully accelerating roughly horizontally, toward the object as it whizzes skyward. But, given all the data in the movie(mass = 10^9 kg; it reaches max height of about 1,400 meters above the desert floor before coming back down; it emerges not less than 2 meters outside their tent), it ought to impart a gravitational acceleration of not more than 0.0167 m/s^2, which is only less than two thousandths the force provided by Earth. Given that the hole was also traveling away at about 117 m/s, the relative velocity would've been in excess of the hole's escape velocity(only about 0.25 m/s), so there would be no such dramatic effect.

Factual error: Owen's phone is a Nokia 3300 which is one the phones which are designed to be wider rather than taller (like an N-Gage). Throughout the film when Owen speaks on the phone he holds it the wrong way around. He holds it to his right ear with the rounded edge of the phone pointing upwards to the top of his head. Holding it this way would mean he'd have the microphone to his ear and be speaking into the speaker. I noticed this because I have the same phone, obviously the actor was not sure which end was which and guessed, getting it wrong. I noticed this during the scene where he phones the girl that got stood up at her dance.
Factual error: In the scene where Caroline finds the conjure record, it is written in ink on the sleeve that it is from "New Iberia Parish". Such a parish does not exist in Louisiana. There is a town called New Iberia, but the parish for that town is Iberia Parish.
