Here is an idea that I wanted to play around with but unfortunately hit a brick wall with. Human explorers have found a less advanced intelligent technological species on a faraway planet. For the most part, we have established a peaceful relationship, engaged in trade, education, exploration of the local landscape and biosphere, learned each others languages, and they understand that the tools we use are not magic but science that is merely several centuries ahead of them. Now one human on the planet decides to have a movie night to improve the morale of the humans who are all a long way from home and act as a kind of cultural exchange with the locals. Since the locals put on a couple of plays for humans, they are fascinated by this opportunity.
Only one problem.
Most of the sci-fi that revolves around non-human aliens and humans interacting with them...might have some subtle specist undertones that we as humans might not be aware of. I remember from the novel "The Killing Star" when a species that bombed our home planet and set out on a system-wide hunt to find and eliminate any survivors, said that they watched Star Trek and came away with the implication that humans would only treat other sentient life as equals if they happened to resemble us, and towards anything else we are genocidal maniacs with phasers at the ready. And that was Star Trek the sci fi utopian ideal that other cultures from other worlds might one day all get along.
So I an now feeling sorry for the person looking through their personal media files trying to find something that won't cause an interspecies diplomatic incident.
So here in lies my question: What movies would you show to our alien friends that will show them that we are genuine in our attempts to be friendly to them?
Edit note: Alright since many comments have asked for clarifying details about these aliens in question (and I don’t want this question closed) I have decided to provide a couple of helpful details. First thing to note is they have a similar psychology to us. They feel similar emotions to us, they have stories and heroes of their own, they have a sense of humor and they have a concept of right and wrong. Second they are not humanoid, they have bilateral symmetry, they have arms and legs, they have a head with eyes, they have the same senses we do (plus or minus a few extra) but that is about where the similarities end. And finally while they understand reproduction is a fact of life, they don’t feel it is proper to show it off to everyone.
