The muskets used in the culminating battle carry props which look like flintlocks. But the British did not used flintlocks in the Restoration era of Charles II. Rather they would have used matchlock muskets.
The film ends with Morgan's impending hanging. Morgan, in fact, followed up his career of piracy with a full royal pardon, a knighthood, a governorship (of Jamaca), and the ownership of three significantly large plantations (on Jamaca). Furthermore, Morgan's death not only did not come at the end of a rope, but peaceably in a rich man's bed. Finally, Morgan was given a state funeral, and his body lay in state for a public viewing at King's House (which was hardly something reserved for a pirate and an outlaw!).
On the way to the Caribbean, a scene has a lantern swinging and casting a swinging light on a canvas background. But as the light swings, a shadow of the lantern itself is also cast against the background, revealing that the source of the light is NOT the lantern, but a spotlight to the right of the camera and out-of-camera range.
Once in Jamacia, Meg is mugged and receives a blow to the face/forehead, by a club. Even though the blow is hard enough to render her unconscious, moments later, when the Governor (who had raced to her rescue) picks her up, there is no mark on her face. There is no blood, no scrape, nor even a bruise. Furthermore, hours later, while being nursed in the Governor's home, there is still no mark on her face. Knocked unconscious by brute force and still as pretty as one's professional glossy! Now that's Hollywood.
Two men easily carry a small chest of gold coin to Morgan. Each one carries the chest with only one hand. But gold is so heavy that, if the chest really were filled with gold coin, it would not, it could not have been carried with such ease. Rather, it would have taken a great deal of effort to haul that chest, even with two men, to the table. So, it is a good thing that gold-colored plastic coins are so light.
At the opening of the theatrical trailer (also in the DVD), before the inserts of two bar girls in a slap fight and a scene of bear wrestling, taken from Anne of the Indies (1951), one sees the name of a ship going away from the camera: 'Sheba Queen.' The letters are inverted, as on a mirror. The ship close-up is not part of the film itself.
One of the pirates is using a fencing foil, as evident by the ball blunted tip (to ensure that the foil cannot and will not penetrate during any thrust). The foil is further evident by a move by the pirate when he had the tip of the foil on the chest of a man. When he leaned ever so slightly into the man, the foil blade began to bend, bow. Obviously, a weapon would be most ineffectual if it bent instead of penetrating its intended victim. But a fencing foil must do just that, least every time there is a fencing match, one or both participants would end up being bloodied.
After receiving a blow to the head, Meg is knocked unconscious and therefore asleep for some time; but upon regaining consciousness, the people taking care of her know her as lady Margaret even when she was not awake to tell them her name.
At the start of the movie is a shot of Trafalgar Square with Admiralty Arch in the foreground and Nelson's Column in the middle. The movie is about pirates during the reign of Charles II (1660-1685). Trafalgar Square was named after the famous sea-battle in 1805 in which he died. The Arch was erected by order of King Edward VII and completed in 1912. Part of the text on it is visible:
"(:ANNO:DECIMO:EDWARDI:SEPTIMI:REGIS:
:VICTORIAE:REGINAE:CIVES:GRATISSIMI:MDCCCCX:)"
Morgan pulls a pistol on Bart. But the frizzen is forward, rendering his pistol inoperable. For a flintlock to be operable, there must be powder in the pan, and the frizzen back and over the pan. In this way, when the cock is pulled back and the trigger is pulled, the frizzen is positioned so that the flint in the cock can strike it. As the flint in the cock strikes the frizzen, two things happen --- first the flint scrapes the frizzen and causes sparks. Second, the act of striking the frizzen causes it to go forward which uncovers the powder in the pan. That powder now lays exposed to the falling sparks which ignite the powder. When the powder in the pan ignites, it flashes and sends a fire through the touch hole, which in turn, ignites the main charge and sends the ball on its way down and out of the barrel towards its intended target. BUT none of this can happen if the frizzen is forward. In that case, IF the cock is back, when the trigger is pulled, the cock will simply rotate forward and stop in a forward position. With the flint having failed to strike the frizzen, NO sparks can be created, and NOTHING can and will happen. No 17th Century fighting man would have made this mistake, particularly one of Morgan's statue and experience.
