Continuity mistake: After the plane has crashed in Las Vegas, Cameron Poe rescues the bunny (his daughter's birthday gift) from the sewer/gutter. The bunny is obviously soaking wet since it had just been floating down the street in a stream of water. Later, when he gives the bunny to his daughter, it is dirty, but dry. It is clear because the ears are sticking up and bouncing, and the fur is fluffy.
Continuity mistake: When Pinball is fighting the female guard on the plane they are struggling, and from one angle her hat has fallen off and from another angle she is still wearing it. It jumps between scenes like this with her hat being on and off.
Continuity mistake: When we see the close-up shot of Steve Buscemi grabbing the doll, he is picking it up with his right hand. But in the next shot, when you see a wider view of him picking it up, it is now in his left hand.
Continuity mistake: When the car hits the control tower and falls. You can see the "azz kickr" licence plate still intact. A few seconds later a crumpled up licence plate that says "azz kickr" is picked up by Colm Meany. That plate is meant to have come from the front of the car, but we've seen before there was no plate at the front.
Continuity mistake: Cameron Poe's stubble length changes noticeably while they are on the plane. At one point when him, the guard and Baby-O are about to jump off the plane after taking off from Lerner Airfield it has almost disappeared.
Other mistake: When the car crashes into the tower, you can clearly see when it goes through that the car is not attached to anything, the rope that was pulling the car has gone, yet when the car lands on the ground you can see the rope still attached to the car.
Continuity mistake: When Diamond Dog puts the hat on in the plane after it's hijacked, he puts it on backwards.A second later, it's on straight without him turning it around.
