At the beginning of the movie when Benjamin is taking the children to Aunt Charlotte's house in Charleston, there is a woman on the street that does not move, and wearing a big hoop dress. She is there to hide the fire hydrant on the street underneath her dress.

The character Benjamin Martin was based very strongly on the real life militia leader Gen. Francis Marion, the "Swamp Fox". In the original drafts of the script even the character's name was to be Francis Marion. However, during filming certain historical sources revealed that Francis Marion was perhaps a very dubious character who was accused of hunting Native Americans for sport and raping his female slaves. Historical debate rages over the veracity of these accusations; but Sony Pictures changed the name of the character to Benjamin Martin to avoid any potential controversy around the film.
