Continuity mistake: As the cars are being stolen from the train car, they're violently dropped onto the ground, yet they don't have a scratch on them. The best example is the vintage Corvette that Vin Diesel drives out of the train car. The car falls at least 6 feet, landing on the front left corner of the bumper, yet seconds later, the car is in perfect condition.
Continuity mistake: The hole in the plastic which is around the vault Han ordered changes after Tej says "You got a 100 million dollars in a safe, are you going to put somebody else's handprint on it?" This is easiest to spot around the palm scanner: at first, it is completely free, but after that line, the plastic suddenly hangs in front of it.
