Goofs

The chase through the London Zoo takes place at night. However the insert shots of various animals were clearly shot in broad daylight.

At the end, David clings to a sweep (pole) stuck in lake's bottom, as his boat drifts a couple yards away. After a closeup on Yasmin's face as she reacts to his response that he cannot swim a stroke, the view returns to David, and the boat is close enough that he can fall onto the back of it and slide off it into the water.

Near the beginning, when Pollock is in the limo with the Prime Minister, the glass partition is raised, and it is very dark such that the driver cannot be seen. Moments later, when the ambassador taps on the glass signaling to stop the car, the glass is clear.

The interior of the Rolls Royce at the beginning changes between shots.

Sloan says he was with the 42nd Highland Fusiliers. The 42nd is, in fact, the Black Watch, and no one from that regiment would ever refer to themselves as anything other than the Black Watch.

There is no reference to the movie's title, "Arabesque". The references are all to the original book by Alex Gordon (pseudonym of Gordon Cotler), which was titled "The Cipher".

There is no requirement that a movie's title be referenced in the film. Titles often change throughout the production of the film, and the final selection is often outside of the scriptwriters' hands.

During most of the dash to the airport to prevent the assassination, it is pouring rain out of a cloudless blue sky.

When David and Yasmin are escaping from a helicopter, the filming crew is visible on the right side of a bridge (in the helicopter's POV).

During the final chase, the helicopter continues to fly past and around the characters on the bridge, while the bad guys attempt to shoot them from the air. If the helicopter had just hovered in place, the shooters likely would have been able to kill the three on the bridge.

Per IMDb Guidelines, this is not a Goof. Plot Holes, "in a nutshell", are "Genuine errors in narrative structure (no personal opinion)." The Guidelines further state, "We're extremely wary of these. By far the greatest number of corrections we get are from people explaining that plot holes aren't really holes at all and were just the result of the original submitter not paying complete attention. Not liking a movie, or believing that you have a better solution for a character's dilemma, does not justify a plot hole entry." However, if the helicopter had not been doing the fly byes it would not have gone under the bridge enabling Peck to drop a ladder into its blades causing the crash. The irrational flight maneuvers are a critical and unbelievable element in the demise of the bad guys.

The Arab character Beshraavi mispronounces the name Mustafa. An Arab educated in English would still say Arab names in their original pronunciation.
