Other mistake: When JM lands at the New Jersey turnpike he has an argument with Craig. When he walks away down the road a car drives by from behind. Someone in the car throws a can at him, shouting "Think fast, Malkovich.". This guy had no way of recognising him from behind. (01:08:55)
Other mistake: When Carol says, "I've always wanted to try soup but there's the fear of drowning," read Deuce's lips. Hes saying her line along with her.
Other mistake: Multiple mistakes are made at the end of the game against the Wildcats. Before the final touchdown, the Wildcats are shown leading 13-0 with 6:00 minutes left in the game. After the touchdown, the Wildcats are shown leading 20-3 with 3 seconds left in the game. Based on Mox's position in the two shots, no other plays happened, meaning that the time and score in one of the shots is incorrect. The clock also continues to run when the touchdown is scored even though it's supposed to stop.
Other mistake: When the student body presidential candidates are giving their speeches, "Monarchs" is on the Gym floor, and not "Wolverines." This is because the school where it was filmed, Papillion-LaVista, their mascot is Monarchs.
Other mistake: Tony Clifton comes on the 'Taxi' stage accompanied by two prostitutes. He introduces one as Melonia, squeezes her breasts and asks 'how is our produce department?' The German subtitles read 'production department'. (00:44:25)
Other mistake: When Porter cuts the fuel line on the car and is about to light it, Carter's henchmen see him and act surprised. Despite having ample time to get out (as any rational person might do), they just sit in the car and wait for it to explode.
