The moment
Michael (Robert De Niro) cradles his dying friend Nick's (Christopher Walken) bloodied head after one last fateful game of Russian roulette.

Why we get choked
Friends in life and war, the two share an inseparable bond that was broken by the ravages of a useless war. We know what the one has done to try and save the other (and his earlier promise to never leave him), so when Michael fails to help Nick, the pain cuts even deeper.

Next: E.T. reminds Eliot "he'll be right here" >

Maybe it's that moment when Wind in his Hair asks Dances with Wolves if he can see that "he is his friend" and tells him that he "will always be [his] friend" that we missed.

Do you agree that this moment is one of the best?
