Goofs

When Alan first oversleeps in his hotel room, the clock reads 9:15 in the wide shot and 9:14 in the following close-up.

(@47:32) When they park the car at the construction site and walk out, the shadow of the building falls about 2m away from the front of the car. But when viewed from the opposite angle, there is no shadow at all. (The shadows in the background keep jumping back and forth in the wide angle shots for about a minute.)

New Hampshire has no national parks. Mount Washington is in the White Mountain National Forest.

Several times Alan is seen passing a gate guard by taxi. The guard just lets him pass, not caring very much, at times taking a foot-bath or even wittingly waving. This is highly inaccurate as in Saudi-Arabia, any visitor's car entering a guarded compound would be stopped, then both engine bay and trunk be searched for car bombs, regardless who's sitting inside.

Going to Makka is not possible without going through check points where officers investigate visitors about their knowledge about Koran.

Alan requests a rental car but is rejected because of his having no international drivers' license. In Saudi Arabia, anybody who has US drivers' license can drive a car with only the US license as far as he is a guest visitor. If he obtains Iqama as a resident, he needs to get a Saudi license.

Saudi passport check gives a stamp written in Arabic, not in English as shown in the film.

The date of the entry stamp in the passport is shown as 09/25/2010, but like most of the world, in Saudi Arabia, dates are written in day/month/year format (25/09/2010).

When Yousef told Alan (Tom Hanks) that he can't meet The king because the king is visiting Yemen, the next scene shows a newspaper where it's written that the Yemen president is having a meeting with the king in the king's palace in Jeddah which is a city in Saudi Arabia not in Yemen.

The passport stamp shows 09-25-2010 as entry date, however the visa on the next page has an issuance date of 07/09/2014, so 4 years later. Also, the stamp doesn't have the right design.

The first time Tom Hanks wakes up late in his hotel in KSA, there's a Muslim prayer call (Adhan) heard in the background. However, his bedside alarm clock shows it's after 9:00 am, and no Muslim prayers occur in that time.
