Continuity mistake: David's [Ralph Fiennes] glass on the table is filled to within about 1" from the top. When he raises the glass to his mouth, the amount is about 1" lower, which may explain why the lemon slice is now floating diagonally instead of vertically. (00:01:36)
Deliberate mistake: David and Jo, each wearing sunglasses, are riding in the boat. When David says, "L'Afrique", buildings along the upcoming shore are reflected in his sunglasses. The camera shifts to Jo, also facing the shore, and buildings with more lights are reflected in her sunglasses. The camera then shifts to a rear view of David and Jo and it is obvious that what was reflected in their sunglasses was not possible. (00:01:40)
Deliberate mistake: David's reflection was shown in the dresser mirror when he was sitting at the foot of the bed. When Jo moves around David, the foot of the bed and the corner of the dresser, though not touching, form a 90° angle and the mirror does not span to the edges of the dresser. Therefore, David's reflection could not be in the mirror as shown. (00:03:25 - 00:30:38)
Other mistake: Right before the "Y" in the road, it could be seen that Richard's speedometer was pointing to the far left, indicating that he was driving at a low speed, such as 5 - 10 MPH. When Richard was looking at the damage to the car, he said, "Smashed headlights, smashed bumper. Must have been going at a fair clip." The damage to the car, as well as Driss' death from the impact, seem severe at such a low speed. (00:07:40 - 00:16:09)
Character mistake: David said, "Camels bite. I hear they like to bite people in the stomach. It's the leading cause of death among the Arabs." This is absurd. Generally, leading causes of death are heart disease, cancer, diabetes, high blood pressure; auto accidents may be the leading cause for certain age groups, and deaths from infectious diseases may be increasing. Resorting to statistics on the deadliest "animals", camels are not even in the top 15. Deer and bees (#14-15) cause about 100 deaths each yearly. (00:24:15)
Continuity mistake: When Jo is talking to Tom (after David left with Abdellah), the amount of separation in her bangs varies, as well as the shapes they form. (00:48:40)
