In The Dark Knight, Heath played the role as a villain called The Joker, and He Was Amazing, it ended up being his last movie which made it a little harder to watch, but in the grand scheme of things, nobody could have done it better than that! In The Patriot he stars with Mel Gibson and plays the role of the son of a French And Indian war hero, and goes to fight in the American Revolution when his father won't. I think it was his best war movie ever. Both movies were great, but they won't compare to the best ones. Don't believe me? "Why so serious?"
