Continuity: 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: In the scene where 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.

Revealing: 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.

Continuity: 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.
