Other mistake: In the turkey shoot the participants have five shots, but Dwight shoots only four times. (00:28:20)
Other mistake: Schindler is having the glass door of his office lettered. The style and size of how it is done changes when the one armed worker comes to thank Schindler as he eats breakfast.
Other mistake: Rudy continually checks the roster to see if he made the dress list. The captain of the team is Roland Steele; the first one to visit the coach about giving up his jersey for Rudy. Every time Rudy looks at the list he scans past the last names for "S" where you should see Steele, Roland. Steele doesn't appear on the dress list yet he dresses every game. Stock, J. (Capt.) appears on the list, so Steele should too.
Other mistake: The inmates are watching "The Godfather"; specifically, the scene towards the end in which Don Corleone is speaking to Michael in the garden. Just before the inmates light the guard on fire, the audio jumps backwards: after we hear Don Corleone say "Whoever comes to you with this Barzini business...", the next line we hear is "I knew that Santino was gonna have to go through all this...", which is from earlier in the same scene. We then see the film and see Don Corleone's lips forming the line that follows the Barzini line, while the audio continues with the incorrect, earlier line. (01:35:15)
Other mistake: Before the opening scene, where there is a paragraph setting up the history of the musical, in the third line there is a spelling error: "it's" should be "its" since it is a possessive pronoun and not a contraction.
