Gibson's a twit, but I would like to point out that "The Patriot" featured a maroon camp. I hadn't known there were maroons, runaway slaves who lived like Africans, in North America. It was an interesting thing to discover.
Now, Gibson's character in said movie raised maize, not indigo, rice or sugar, as a planter in South Carolina would have in the 1700s. The costumer had people travelling in dress clothes. Which was even less likely then than now. I would be amazed if there was that much lace in the whole of South Carolina, as there was in that film.
