Which movies have been most effective at expanding your moral circle?

The Dominion documentary helped me viscerally grasp the importance of farmed animal welfare:

Hotel Rowanda, Schlinder's list, and blood diamonds were all influential in increasing my moral seriousness as a teen

Life in a Day.

I'm not sure about the level of EA congruence, but Lord of War helped me understand the effect of the small arms trade on people in sub-saharan Africa, which I didn't previously know about.

Not movies, but watching Star Trek as a teenager strongly influenced my views towards non-humans. 

While the focus is typically on attitudes towards biological aliens, a couple of episodes are centred around the rights of artificial intelligence: The classic Next Generation episode 'The Measure of a Man', and Voyager episode 'Author, Author'. Though they both focus on specific individuals (namely Data, and The Doctor) they do touch on broader consequences and reasoning.

The movie Joker makes a good case that many criminals are created by circumstances, like mental illness, abuse and lack of support from society and other people. I still believe in some form of free will and moral responsibility of an individual, but criminals are also to some extent just unlucky.
