Factual error: In the Abu Simbel scene, watch closely when they show a side-view shot of Jackie, accidentally depicting the shores of Lake Nasser in the background. This reservoir was built only in the 1960s and didn't exist at the time the movie is set in (1930s). (In fact, the whole temple had to be cut from the rock and moved to higher ground following the completion of the Aswan Dam, so the "original location" was no more available for the film crew.)

Factual error: The carriages on Hannay's train feature British Rail 'class' totems on the windows. These didn't appear until the 1950s, yet it is supposedly 1914.
Factual error: During the early chase, a policeman fires a shotgun at the blue LTD. Each shot is supposed to hit the trunklid, as it comes loose, then flies off, yet the lid is never damaged by the bullets, as if they are passing through the lid, hitting the hinges and lock without leaving any holes or dents in the lid itself.

Factual error: When the bad guys collect the $100 million in cash from the vault, it's been laid out in just 2 suitcases. According to US government specifications, that much cash (it is mentioned in the movie that it is in $100 bills) would be a single pile nearly 50 feet high (about 10 times what is shown) and 1,000kg - a full ton of weight.
Factual error: The credits roll closes with the caption "San Francisco...seven thousand miles away from Casablanca." San Francisco is less than 6,000 miles away from Casablanca. (00:03:20)
