Factual error: Summer and Carmen are at the saloon and catch on the local news the report of the kidnapping. The scene is set in Tuscany, Italy, but the news anchor is Spanish actress Paz Vega, speaking with an obvious accent and mispronouncing words. To make the whole situation even more absurd, she is supposed to portray a native Italian speaker, "Giulia Carni": the last name is Italian sounding but nonexistent in reality, and the headline used for the news report, "Nonna-napper", "kidnapper of grandmother" has such an awkward and unnatural sound and feel in Italian and for an Italian audience, that nobody ever would use it.

Factual error: When Tony first goes to Johnnie's house a satellite dish can be seen mounted on the house in the background. Not in 1973. (00:57:00)
Factual error: At the beginning of the movie, the Battle of Scheveveningen (1653) is depicted. However some of the British ships sport a gaff-rigged mizzen spanker, which was not introduced until late in the next century.
Factual error: The producers took a lot of pride in using period-accurate furniture and clothing. But the family's house and furniture aren't remotely accurate for their actual situation. The table, the chairs, the house with a sleeping loft - all those took technology and manpower that they didn't have, and we've already seen that they had nothing to trade either. And they have more furniture than could have fit in that wagon.
Factual error: The search that cracks the case is nonsense from a simple logical standpoint. There are three people, whose deaths have never been related together, but that all died because of tetryzoline poisoning. Entering all three of those names in google would not produce relevant results or even narrow the spectrum, because it's three unrelated deaths. (01:08:40)
Factual error: The girls missed the bus for the football match because one of them got stuck. Luckily they manage to stop a passing truck and ask for a lift to overtake the bus, which, they stress, was bringing the girls "to Trabzon." When their custodians see them cheer on TV and drama ensues, the match is Galatasaray (GS) vs Trabzonspor (TZS); the home team is Galatasaray, so they should be playing in Istanbul.

Factual error: At the beginning of the movie when Danny Glover is sitting at the chessboard, the pieces are lined up wrong on both sides of the board. If Danny has the white pieces, the king should be on his right. The black king should be on the opponent's left.
Factual error: A library assistant is showing his cellphone to a Fed. The Fed pulls out his gun and shoots the assistant from about 8 inches away into his left temple.

Factual error: The limo used in Louisiana has a front license plate and it's a Louisiana plate. Louisiana only issues a rear plate.
