Other mistake: While the fire on the oil rig burns all around, Mr. Freeze grabs Belson, then orders him to go find Barbara (to do the transplant). When it cuts to a closeup of Freeze, the reflections of Belson on Freeze's eyeglass lenses are not reversed as they should be. (00:53:00)

Continuity mistake: At the start of the film, Eggman is chasing Sonic through the streets and there is a shot of the city skyline down a street behind Sonic as he makes a turn.

Continuity mistake: This is near the end of the movie when Charlie Brown is running to catch the Little Red Haired Girl before she boards the summer camp bus. As Charlie encounters obstacle after obstacle he runs into the "Kite Eating Tree" and asks for help. A kite falls down and he gets tangled up in the string and he is pulled away. There is no ball of string at the end. Several cuts later when everyone is amazed that Charlie Brown is actually flying a kite and following him, a ball of string magically appears and Charlie Brown is holding it while running and flying the kite.
Continuity mistake: When Norm barges into Mr. Greene's office to confront him about rigging the announcement, Mr. Greene's ball chair is on the rug positioned close to the edge and located near to the centre, but when Norm goes to leave the room about a minute later, the ball chair has moved much nearer to the opposite end of the rug. (00:59:55 - 01:00:50)
Continuity mistake: When the crime bosses meet up at the casino, in the exterior shot, there are a few items on the desk including a bottle, an ash tray, a plate with a slice of pizza and a newspaper.
