When Schindler convinces the head and guards of Auschwitz, first by bribes, to let the women who accidentally got sent there free as well. Then he convinces the guards to let the children go by saying that their smaller hands are needed to polish the inside of shells. The kids never ended up doing that.
Despite being perhaps one of the most powerful tear jerkers of all time, it has some pretty awesome moments.
Oskar Schindler: I know you have received orders from our commandant, which he has received from his superiors, to dispose of the population of this camp. Now would be the time to do it. Here they are; they're all here. This is your opportunity. Or, you could leave, and return to your families as men instead of murderers.
the guards slowly leave
One for Steven Spielberg, for just making the movie. For him, it was more than a movie, it was his heritage as a Jew.
Spielberg himself gets a Real Life one for refusing a salary for this movie, as he claimed it would be "blood money". Doubles as a Heartwarming moment.
