New this week Factual error: At the beginning of the movie, they are leaving High School for summer break. However, all of the kids are 13. (For instance, Stan is having his Bar Mitzvah, and Ben notes later on that he will be 40 the next time IT comes around.) However, most kids start High School when they are 14 or 15. That all the kids are 13 at the end of High School is a glaring mistake, or they are all advanced, which I doubt, as Eddie does not know the difference between "placebo" and "gazebo."
Factual error: Eddie specifically tells the gang not to take his mom's "Delicious Deals" snacks because his mom loves them. But Delicious Deals are made by Mrs. Freshley, a company that was not founded until 1994. The boxes used in the movie even include the modern design that can be found today in most Dollar Tree stores.
Factual error: When Stanley is at synagogue practicing for his Bar Mitzvah, and the Rabbi tells him to close the book, he does so - and a clear shot of the book cover from Stanley's left shows that the book (in Hebrew) is upside down. Hebrew books read right to left - the cover should be on Stanley's right, right side up.
