Deliberate mistake: In the scene in which Ace is in the asylum, he breaks into a storage closet to view Finkle's belongings that were left behind when he escaped. At first the doorframe is such that the door closes against about an inch of wood, meaning the lock would be behind this wood, so Ace couldn't pry it open.

Deliberate mistake: In the final stadium scene, the scoreboard sets forth that it is the 2nd quarter, 3rd Down and 6 yards to go. The game clock indicates that 15 minutes are left in the quarter. The announcer indicated that it was the start of the 3rd quarter, and neither team kicked off.
