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: 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.
