Goofs

In exterior shots of Omar's office we see Joan's camera flash go off. However, in the interior shots there is no flash from her camera.

The jet's afterburner is not on in the third shot after Jack activates it.

At the beginning of the movie, the amount of zinc oxide on Joan's nose changes with each camera angle.

When Ralph realizes that he is standing on coals, he turns to his left and starts to walk. A closeup of his feet shows him turning to the right.

Like most aircraft, the F-16 stores some of its fuel in the wings. Plus it was prepped and ready for a flight, which means its tanks would be full. So, when the wings were torn off, the resulting fuel leak would have burned the jet up immediately.

The Nubian man that Jack is wrestling who wants to win Joan's hand in marriage can be seen wearing a wedding ring.

The man may be wearing a ring on the finger that would be considered as traditional for a wedding ring in western culture, but that does not mean that's what it refers to in his own tribal culture.

Obvious stunt double of Joan in certain shots of the train scene. Stunt double has darker hair and is wearing brown leather sandals instead of the huaraches Joan is wearing as she leaps on the train.

When Jack releases a rocket while sitting in the F-16, it clearly falls right in front of the left wheel, which should make moving forward impossible. Without anyone removing the fallen rocket the plane could not have moved forward.

After Ralph hits the tunnel wall when he falls off the camel, the camel is facing incorrectly away from Ralph immediately after we hear the sound of Ralph crashing against the wall. On top of that, the camel is tied up securely to a wall; then the camera cuts to the other side and the camel is now facing towards Ralph and still tied securely to the wall.

Many details reveal the F-16 to be fake including the belly (big bulge where the main landing gear attach).
