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.

Norm answers Keenan Wynn, and is told by Cliff that is correct and that his memory is OK. Wynn was the antagonist in the second movie, 'Herbie Rides Again' (reprising his role from the 'Absent-Minded Professor').
