La vita è bella, a movie wherein the occupants of a concentration camp collaborate to help a child. It’s not a movie about saving many people… but I’d say it involves altruism and self-sacrifice.
Speaker for the dead (Ender’s game series part 2), wherein the protagonists encounter two alien species and figure out a way to live together. This one does qualify as saving many “people”, but it’s less purely altruistic. Bonus: There is a cool AI in a key role ;-)
