Factual error: In the chemistry lesson on alcoholic fermentation there is written on the blackboard: H6P5O11 -> cane sugar, which is plain nonsense. (00:34:00)
Factual error: The movie opens on Halloween in Brooklyn. To show how crazy things were in Brooklyn, they show a baseball game being played by the Brooklyn Dodgers that day at Ebbetts Field and a big fight breaks out. The baseball season is and was over (including the World Series) well before Halloween. So there is no way they could be still playing on Oct 31st The only exception was in 2001 when games were postponed due to the 9/11 attacks and the season didn't end until November.
