* This movie has Jack Sparrow interacting with two historical characters: King George II and Blackbeard. Edward Teach, the historical Blackbeard, died in 1718 at age 38, played by the 68 year old Ian [=McShane=]. George II became King in 1727 and the movie has him appearing to be much older than the 44 years he was in 1727 (he's portrayed by Richard Griffiths who was 63). '''However''', Jack referred to Blackbeard's real life death, or more specifically his beheading after the Battle of Ocracoke Island. Backstory explains Blackbeard surviving by bribing Robert Maynard (the man who killed him in real life) into claiming that he slew Blackbeard and took his head. The 1740s-date also explains how both George II and Blackbeard are in their 60s (if Blackbeard faked his death). UsefulNotes/FerdinandVI of Spain has a brief scene in the movie and he became king in 1746.

* Jack mentions that he supports "the missionary's position" when Philip is arguing with Blackbeard over Syrena. Intended to be an obvious DoubleEntendre, but the term "missionary position" was first coined by professor Alfred Kinsey in 1948 during his famous study on human sexual behavior.
* When discussing Philip with Scrum, Jack offhandedly refers to the missionary as a "bible-thumper", a mostly American/Canadian term that would not be invented until 1923.

* The Union Flag is the current version incorporating the red saltire of Saint Patrick's flag representing Ireland. This first flew in 1801 following the Act of Union 1800.
** Made a bigger slip up considering the previous films used the correct rendition of the Union Flag (the one lacking the Saint Patrick's cross).

* Theodore Groves is referred to in both dialogue and the credits as "Lieutenant Commander". However, this rank wasn't created in the British Navy until 1877. Groves can only be a Lieutenant or a Commander, with the latter being more likely in serving as second-in-command to an Privateer Admiral (Barbossa).

* Jack and Angelica jump into the Thames to escape King George's soldiers, and are shown swimming in clear water. The River Thames of the 1740s was a slurry of waste and a fall into the water could--and often did--kill.

* Several of Angelica's outfits include underbust corsets. Eighteenth-century stays were underwear, and provided support for the bust; underbust corsets weren't invented until the Victorian era, when they were still underwear. An underbust corset worn as decorative outerwear, with an hourglass silhouette, shaped to a point between the breasts, is a modern costume element.
