you gotta add enemy at the gates, ill grant you it isnt a traditional survival flick but coering yourself with corpses to keep from being killed sounds like survival to me.
and ditto with behind enemy lines.
last of the mohigans had a survival/tracker feel to it.
i liked the part in lord of the rings when aragorn/strider shows his survival skills while taking the hobbits to rivindell.
i liked the book my side of the mountain but the movie sucked.
and of course RAMBO all of them are great but i think they changed the idea of the movie in 2 and 3, first blood is a true survival film because he faces himself psycologically, faces his enemys, and faces nature. in the book he actually goes through many psycological changes as he goes through the mine but it didnt come across as well in the film. in 2 and 3 he pretty much goes on a killing spree and is relitivly invincible. which is cool too, but i liked the post tramatic stress mood of first blood
