Factual error: When Reese Witherspoon's character is sitting at the desk reading, there is a cheerleading trophy and the cheerleader on it is wearing a mini skirt, - they didn't have mini skirts on the cheerleading outfits then. (01:08:20)
Factual error: Leonardo da Vinci's painting, the Mona Lisa, was originally painted on wood, impossible for it to have been unrolled after taking it out of the canister. Also, if it hadn't been painted on wood, it would have been painted on canvas, which doesn't stay partially rolled after you take it out of a tube of some kind. It would not have been painted on paper. (00:23:55)
Factual error: When Sally is leaving to rescue Gilly from her boyfriend she asks the Aunts to look after her children. The Aunts then say that they will take the children with them to the solstice celebration. A few days later when the cop is interviewing Sally he gives the date as March 8th. There are two solstices each year, one in December and one in June. Since this film takes place in early March, the Aunts could not have been going to a solstice celebration.
Factual error: The movie is set in 1971, but during the start of the motorcycle race several of the bikes are obviously early 90's Honda CR's and Suzuki RM's. You can tell this from the disc brakes on the front wheels of the bikes and the 90's style plastic fenders and bike colors. Bikes in the 70's generally had metal fenders and definitely no front disc brakes.
Factual error: In the opening narrative about the first person to call out "America", as the ship passes the Statue of Liberty, it's traveling in the wrong direction - with the Statue entering the screen from the viewer's left and moving toward the right; a direction that would have taken the ship from Manhattan to Staten Island (or through the Straits into the Atlantic).
Factual error: Beatrice is a different woman in this movie than the first movie. The Beatrice from the first movie is the lady who asks Uber and Jacoille to scare her child so he could do his homework.
