im gonna say jeramiah johnson, not my favorite movie, but the question is best movie ever, so ya, its a movie i could watch over and over and not get to tired of it. it has a good story line, the acting isnt cheesy, and its just plain bad ass.
I'm not sure, but right now I think I will say BEN HER. Charlton Heston is great in all his movies. Plus it is a long movie. I feel like I've seen something.
Braveheart has to be a personal fav. As far as best movie ever i have to go with Alien simple because at the time you had geek sci fi and horror,it was the fist movie to really combine the two...plus how can you not love the cute face hugger?
