Braveheart is my very favorite movie I think of all time and it's a shame I have to feel the way I do about Mel now. I still love the film, I just don't like the real him very much anymore. If you were talking war battle I might say Hamburger Hill for some seriously twisted battle scenes but Full Metal Jacket and Platoon both rival it for some scenes.
I'm going to take huge crap for this, but the battle for Helm's Deep in LoTR, The Two Towers or the battle outside of Minas Tirith..just such incredible odds and these horrific things running in at you en masse.
Not always epic scenes but some of my favorites are in -
The 13th Warrior - cold battle scenes! Shivver Enemy at the Gates Black Hawk Down Tora! Tora! Tora! - available to Watch Instantly
All 6 star movies for me!
The 300 and Braveheart had great scenes and I really liked the beginning of Saving Private Ryan although I hated the rest of the movie.
Yes, it's a great movie. One of my favorite scenes from any film is in there. When Ahmed Ibn Fahdlan is sitting with the Vikings and begins to understand their language. I thought that transition was brilliant.
