Factual error: When Buck first sees the videotape left behind by Pastor Billings, Bruce Barnes tells him about a prophecy contained in "Daniel Nine, Chapter 27." As a pastor, Barnes should have known that the Bible is divided into chapters and verses. He should have said "Daniel 9:27," "Daniel Chapter 9, Verse 27," or "Daniel Nine, verse 27." The point is, "27" is the VERSE, not the CHAPTER. (01:15:05)
Continuity mistake: Whenever they are supposedly in the United Nations building, there is an enormous window where we can see the Bank of Montreal and Canada Trust buildings in Toronto.
Factual error: The airline pilot's hats were reversed. In the airport scene, the captain was wearing the First Officer's hat and the First Officer was wearing the captain's hat.
Revealing mistake: The pastor knocks down a large wooden cross in his church with what sounds like a hollow Spalding ball. That cross must not be made of very sturdy stuff. Actually, it looks like the bottom of the cross was not affixed to anything. A stiff wind would have knocked it over. (00:54:22)
Continuity mistake: When Buck enters Ivy Gold's apartment, Ivy's roommate holds the door open and moves aside to Buck's right. In the next shot when the door shuts behind him, she's on Buck's left.
Factual error: Where Buck Williams goes outside to report on the attack he has an XL1 camera with him. We see that he grabs the microphone from the camera and uses it to make his report but in fact the XL1 camera microphone is not wireless or has a long enough cable for him to be able to pull the microphone off the camera and use it. (00:07:50)
Continuity mistake: What time does the rapture take place? It's late at night on Ray's plane, which is over the Atlantic. Hattie's afraid Buck's laptop might wake some of the passengers. And when Ray gets home, it's clear that his wife and son were in bed at the time they vanished. But Chloe is driving in broad daylight at the time of the rapture, and comes upon a chaotic accident scene that has just taken place. Chloe was also onthe phone with her mom apologizing for missing her brother's birthday party that afternoon. Finally, when Ray arrives in O'Haire after turning his plane around, it's daytime. Very inconsistent.
Factual error: The airline pilot wears a coat with captain's ranks on the sleeve but he's also wearing shoulder boards with a U.S. Navy Captain's insignia (you can tell by the star between the button and the stripes). Coats are worn either with the stripes on the sleeves or on the shoulder but never both. In another scene, you will see him having taken his coat off and still be wearing another set of shoulder boards, this time with airplane insignias. So he was wearing those shoulder boards underneath his coat with that other set of shoulder boards. Shirts have shoulder loops not boards.
Plot hole: The attack on Israel scene leaves one important question: How would it have been possible for the bad guys (the Russians, or Arabs, or whoever) to stage such a massive surprise attack without being discovered ahead of time? Anyone who is knowledgeable in modern warfare would know that an operation of that scope would require a considerable amount of logistical preparation that could not possibly go unnoticed, especially considering the capabilities of modern spy satellites.
Continuity mistake: Buck films a man speaking during the attack on Israel by the Russians. All around him in the air the Russian planes are exploding and are seen everywhere. Later, when Buck watches the tape again there is only the man talking with no explosions seen behind him.
