I was a little dismayed to learn that this production did not portray the facts as accurately as is possible. The film itself is very good and kept my attention, and after it was over it had interested me enough to want to know more about Blackbeard. So I did some research, and that's when I learned that what I had just seen was not necessarily how it happened...
For one, in this film Blackbeard is shown always operating on his own, on one ship, when in fact he often had a mini-flotilla of three or four vessels. Another surprise was that his famous flagship, Queen Anne's Revenge, was run aground in North Carolina (some say intentionally). Somehow the film failed to mention this seemingly important event.
The story is told through the eyes of Israel Hands, Blackbeard's 2nd-in-command. That much is true, for Hands was part of the crew, but the film does not mention that Hands actually captained another ship in Blackbeard's group; furthermore, the film shows Blackbeard deliberately wounding Hands to save him from a coming battle, while the historical account of the incident is that Blackbeard shot at another sailor, missed him, and the bullet found Hands by chance. Blackbeard's reason for shooting? "That if he did not now and then kill one of them, they would forget who he was." This is hardly the same reason for shooting as the film portrays.
Lastly, and rather disturbingly, the film shows Blackbeard bringing his new wife to his ship (after a brief attempt at retirement) and allowing his crew to gang-rape her; the voice-over in the film states "she was never heard from again." While I suppose that a corrupt individual like Blackbeard was certainly capable of such an act, I could find no historical reference or basis for it. In fact, if anything, it appears he was more of a "ladies' man" and, according to author Robert Lee "few pirates treated women or girls with greater respect than he..." Given that, it's puzzling why this film would portray Blackbeard authorizing such a heinous crime.
The sad part is, I really enjoyed the film and thought it was well done. It was only after I did some research that I learned the film does not do the best job in presenting history as it happened. I give it 3 stars for entertainment value, but it loses two for playing "fast and loose" with some of the facts.
