Continuity mistake: In the beginning when they are in the comic book store, they are asked if they were paid for likeness rights for the comic book and Jay and Silent Bob said no. Towards the end of the movie when silent Bob gives Banky the long legal spiel during the shootout, silent Bob tells Banky they had an agreement on the likeness rights and they were supposed to be notified before it was transferred to another medium. So, in the beginning of the film they said they had no agreement on likeness rights and towards the end they said they did.
Suggested correction: They never said that they weren't paid for the comic likeness rights. Jay immediately responded that they haven't seen a dime of a movie check. Currently watching it.
Continuity mistake: In the scene between Chris Rock and his assistant, Chris Rock's grip on the coffee cup changes.
