Altered Personality
I saw this as a child.
The scene in which the crowd gathers to watch the plane crash pilot burn to death, and Robert Redford is forced to club his friend over the head to knock him senseless and end the pain, left an indelible impression upon me.
I think that this scene displays the worst in humankind - that cows-in-the-cornfield tendency to mass around terror, horror, sadness or misery and stare unblinkingly - even while munching on snacks!
I remember watching "Alive" about the plane crash cannibalism, and just when they were using a fork to ply some frozen human flesh for food, a woman in the next row said "Honey, go get some more popcorn."
God. People. Watching them move, slowly, in large packs, has sickened me ever since seeing this movie.
