Continuity: In the scene when Jack, Joan and the Jewel are trying to jump on the moving train. Joan is wearing slip on shoes, however once she has jumped onto the train and falls over the side her shoes have changed to buckle sandals.

Continuity: When Joan meets The Jewel for the first time in the room where Omar is holding him prisoner, Omar enters and greets Joan. As he leaves, the shot shows Joan with her back turned to Omar and Omar is heard off-camera saying Joan looks pale. How does Omar know how Joan looks if he doesn't see her, and there is no mirror on the side of the room where they are chatting?

Revealing: 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.

Continuity: Towards the beginning of the movie (with in the first few minutes) when Joan and Jack are on the boat discussing their day, the amount of sunscreen on Joan's nose changes from a lot to not much and back to a lot again.

Factual error: The tiny missiles on the F16 are shown as being attached to some sort of flexible metal framework which bends and shifts as the plane moves along the ground. The F16 is a supersonic fighter - any such thing would be ripped clean off the wing at speed. The missiles carried by the F16 are attached to streamlined 'hard points' under the wing, or the wingtips themselves.

Plot hole: Jack says, "Our anchor was stolen and we were drifting for days." It's a sailboat, not only does it have sails but it has a motor too. They could easily maneuver the boat.

Factual error: In the scene where Mike Douglas and Danny D. are trying to get into Omar's castle, they argue with Rashid. Rashid orders the guards to ready their weapons. As the guard to Rashid's left cocks his M-16, you can see that the bolt is already open, so the rifle didn't need to be cocked. Also, you can see into the receiver and there are no cartridges in there - and you should be able to see the one at the top of the magazine.

Other: When Jack shoots the plane, lots of pieces of wood fly out. Where did the wood come from? The plane is all metal.
