Factual error: At the end, Josh and Nat both run onto the Eurostar platform when they do not have a train ticket - this would be impossible, since there are ticket barriers and security.
Factual error: At Liberace's funeral, when the priest concludes his prayer, the congregation responds, "And with your Spirit." This response has only been part of the English-language Catholic Mass since 2011. In 1987, the response would have been "And also with you."
Factual error: In the beginning of the film, when Nick flashes back to 1922, he mentions that the buildings were taller, and a shot of the Empire State Building is shown. But construction on that didn't even start until 1931. Even the Chrysler Building didn't start construction until 1929.
Factual error: Tilda Swinton requests a flight from Detroit to Tangier, Morocco, but it must be an all-night flight since she and Tom Hiddleston are vampires. They end up accepting a flight connecting through Madrid. Flying west to east, it would be impossible. If they leave their home at sunset, say 6 p.m. Detroit time, and take off around 8 p.m. Detroit time, it is already 1 a.m. In Spain. Toss in the travel time and they will be landing in Madrid in the early morning, which would kill them.
Factual error: When David Lyons checks the map on his computer where it shows where you can travel with Coach America, it shows all stops and routes. But Southport isn't a stop or on a route. Closest stop is Wilmington. (00:17:43)
