Plot hole: The wolves seem to conveniently make an appearance to further the story, only to disappear in other parts. They are there for Belle's dad at the beginning and Belle when she tries to escape the castle initially. When Belle's dad leaves the castle after Belle takes his place and when Belle is freed to save her dad, they are not there.
Plot hole: In the beginning after Flint buries the treasure, he kills all the men that are with him. The pistols he has are one-shot pistols, so there's no way he could kill 14 men using only two one-shot pistols.
Plot hole: How did Professor Krassman get shocked into being a frog? The electronic device doesn't even touch his head.
Plot hole: When Quasimodo is revealed to the crowd during the Festival of Fools, someone identifies him as "the bell-ringer from Notre Dame." This is the first time Quasimodo has ever left the cathedral, so he shouldn't know that.
Plot hole: I never understood this... if the Good Ole Boys were running so late that the place was already closed, what would the Bunker have done if the Blues Brothers Band never showed up in the first place? There would be no band playing at all and then the amount of beer bottles being thrown around would be 100 times more than what was thrown at the Blues Brothers playing that first song. What would Bob have done with no band showing up at all? So technically the Blues Brothers saved the day.
Suggested correction: Hardly a plot hole if what they did was save the day for the bar. The original band not showing up is just really lucky for Jake and Elwood; the only thing that could have saved them doing a gig and not have the band members leave again. Without any band, the bar would probably just be more deserted, rather than full like it was.
Plot hole: Why is that shark machine even there? The only reason it's there is to help the plot, and I don't see how it is of use to anyone in the corporate world. If the shark just ejects the fish it turns into fish heads out to sea, there is too much chance they will be ruined by carnivorous fish or weather before they are picked up. And fishing companies should know better.
Plot hole: Mr. Cranston asks Denise to be the accompanist for the school's production of "Chicago". This is an error. In the year 2009, in which the film is set, this would be impossible since the licensing company which has the theatrical rights for "Chicago" restricts the show from being produced (even by amateur groups and schools) anywhere in the greater New York area while there is an open-ended production running on Broadway.
Plot hole: When Eddie Mannix first views scenes from the movie Hail Ceasar there is a scene depicting Saul of Tarsus (St Paul), but the movie-in-movie's climatic scene and speech are set at the crucifixion of Jesus which happened several years before the events depicted as happening to Saul / Paul.
