Character mistake: Congressman Weitz tells the FBI task force that Kazahrus is an "absolute monarchy." Director Hirst interrupts him to state that this means "the order of succession is based solely on heredity," which she implies is well-known to students of civics. An absolute monarchy is one where the monarch's powers are unrestricted (such as by legislative or judicial branches of government). Hirst is describing a hereditary monarchy, but not all hereditary monarchies are absolute (for example, England's constitutional monarchy is hereditary), nor are all absolute monarchies hereditary (the Vatican's elective monarchy is absolute). What Hirst says is true of Kazahrus, but not of absolute monarchies, the term Weitz was defining. Weitz is presented as an expert on the topic, but doesn't correct her.
Continuity mistake: When Rich blows up the propane tanks with the flamethrower, he starts to raise the barrel as the explosion goes off. In the next shot of him, the barrel is straight again.
Revealing mistake: Near the end, you're able to see the device used to blow open the kitchen door to make it look like a bomb went off. (00:34:55)
