Other mistake: Based on the location of the barber's chair with the picture window in Todd's barber shop and the layout of the exterior of the building, there is no possible way that the chute behind the chair would be able to dump the bodies directly into the basement without going through the center of Ms. Lovett's shop.
Other mistake: In his search of Giselle, when Edward knocks on doors 209 (hissing cat), 405 (barking dog), and 714 (purple guy), the funny thing is that in all three close-ups the three door jambs/trim have the same paint glob markings. The actual doors were changed, but the jamb/trim remained the same for all three shots. (Only visible on widescreen DVD). (01:04:05)
Other mistake: During the "Come Together" sequence when all of the business men have their big dance number, if you look to the right closely, one of the business men trips.
Other mistake: During the baseball game, Ryan's team was in the field first meaning they were the home team. After Chad scored giving his team the lead, Ryan's team should have batted again since, according to baseball rules, home team bats last.
Other mistake: In the scene where you first see Tracy in class, one of the boys speaks and the subtitles reads," Ms. Whimsy, I can't see the board again." When Tracy says it, the subtitle reads Wimsey.
