Other mistake: While Baz, Fin, and the others are on their way to Matt at Van Nuys Airport, they're blocked in every direction by police cars, and there's a closeup of the rearview mirror which shows their vehicle's clear view through the back windshield, so we can see the police patrol car behind them. The problem is that the view out the vehicle's back windshield is not clear, but actually obscured by camo netting.
Other mistake: The Hollywood Sign has 9 letters - "HOLLYWOOD." When the Hollywood letters are flying through the air toward Fin and the others, there are at least 8 letters in the sky, but when Nova, Fin and the others are driving away from the bridge we can see "L, Y, and O" still up on Mount Lee, which means that only 6 letters should have been in the air earlier.
Other mistake: After the bridge rescue, when the wind picks up the letters of the Hollywood Sign are uprooted and take flight, and we see the "Y" flying through the air, but later when they're driving away we can see Mt. Lee behind the car with the remaining letters, and the Y is still mounted there.
Other mistake: When Baz decides to speed through the area surrounded by police cars, there's a closeup of the vehicle's rearview mirror showing the reflection of a state police patrol car that's behind them, but the problem is that Baz's vehicle does not have a rearview mirror, as seen in all the exterior shots.
Other mistake: During the scenes at the liquor store and in the surplus warehouse, most items on the shelves have tape covering their brand names, and even all the liquor bottles and other items have been turned around to hide their brands.
