Revealing mistake: When Jack and Joan escape in the F16, if you look at the back wheels, you can see the car driveshafts that drive the wheels. Jet aircraft don't have driveshafts.

Revealing mistake: Joan gets splashed by Jack's water skis and goes inside the boat to watch a picture of the two of them on a tropical beach. The picture is blatantly fake: Jack's legs become invisible at one point, his skin looks wiggly were it's been pasted and no shadows match at all.
Revealing mistake: Inside the train, a couple of the musicians can't help staring at the camera.
