Factual error: Near the beginning of the film, a scene opens with the subtitle 'New York'. Strange, these New Yorkers drive on the left.
Other mistake: In the 'Macavity' dance, Demeter makes a mistake with one of her moves and makes an "Oops." face.
Continuity mistake: When Otis gets off the tour bus and comes over to kiss Josephine, his hair changes from processed to natural, before he kisses her.
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).
Other mistake: When a Japanese newspaper is shown publicizing Jackie's performance, the headline above the photo actually reported that the Japanese budget had been approved by parliament.
Factual error: When testing the new phone installation, the engineer only dialled the number, and not the area code, as you have to do on a mobile phone.
Continuity mistake: The young son of the Chinese owner of the violin is near-sighted and his glasses have concave lenses. When he attends the auction as an adult he is far-sighted with incredibly thick convex lenses.
Factual error: In the big professional Latin dance championship scene at the end of the movie, the competitors perform four dances: the samba, the cha-cha, the paso doble, and the rumba. In reality, however, a professional Latin dance championship, regardless of where you go, is almost always a 5-dance event: a cha-cha, a samba, a rumba, a paso doble, and a jive. Rumor has it that a jive sequence was originally supposed to be part of the competition scene but was cut from the final version of the film for unknown reasons.
