The 58-year-old actor, who won an Oscar for best direction for the film, said he wanted clarity in the fight scenes and did a lot of detailing to achieve that, reported Contactmusic.
"The thing I wanted out of the battle sequences was clarity. I've seen a lot of these battle movies and they just turn into mush.
"I broke it down to archers and horses and hand-to-hand and who had the high ground and the low ground, everybody was clearly delineated, even though it was often the same bunch of people playing different parts," he said.
Gibson also revealed the person who came closest to death on the sets of 'Braveheart' was himself.
"There was a horse that nearly killed me. He had a good trick where he did this whole rear-up thing, but he'd also fall backwards, which is a problem if you've fallen off first and you're behind him.
"He did that to me. My stunt double ran in and pulled me out of the way just as the horse fell," he said.
