Continuity mistake: After Masoudi loses on the first question in the rematch, Sedgewick and Deepak are clapping while facing him. It cuts to another camera and they are facing Mr. Hundert and not clapping. (01:25:05)
Other mistake: When Mr. Hundert is chauffeured to Long Island for the second competition, he looks at a St. Benedict's Yearbook page on which the photographs of the original three contestants appear. The heading on the Yearbook page is prominently misspelled "Triumvers" instead of "Triumvirs," in this film whose focus is Roman history.
Character mistake: Throughout the whole movie Bell is left-handed taking tests, throwing baseballs, and everything that he does. As an adult he's right-handed.
