I was watching Saving Private Ryan recently and I just love Captain Miller's last stand. Its heartbreaking and a good send off to such a great character.
Great last stands seem to be hard to come by as of late, but there have been several that really hit you hard; usually it comes when one of your favorite characters decides to sacrifice themselves for the good of the people. Every now and then, a last stand can simply be badass, like in Matrix Revolutions.
So what is your favorite last stand in a movie?
