Movies such as Gravity, Arrival, or the upcoming Passengers and Life films showcase the persistent human curiosity about outer space and who else (if anyone at all) is out there. We’re no longer in the era of little green men coming to invade the Earth in their silver flying saucers to abduct us or otherwise probe our brains. Cinematically speaking, how has the human vision of extraterrestrial life and exploration changed over the years? How have certain historical landmarks in the space program transformed what moviegoers want and expect to see in outer space-themed films? Has the recent media coverage about a possible mission to Mars in the not-too-distant future shifted the cinematic focus away from an interest in aliens to issues of human evolution/multi-planetary colonization? Is there something else at work here?
An interesting topic, for sure. Although I don't have the a very eclectic understanding of science fiction in cinema, I wonder if there has been a shift from the foreign/invading extraterrestrial to a interior extraterrestrial. That is to say, I have always perceived a shift from the flying saucer alien to the kind of alien that takes the form of human; an alien that changes our perception of the human body as human. Movies like Alien (where the alien is born from/comes from the human body) and Invasion of the Body snatchers. One might also consider Men in Black and Under the Skin. What we consider to be alien has, in some instances, become remarkably more human, and I think this would be a fascinating angle to take for this topic. – Dethlefs5 years ago
The movies tend to change with science. The more things science figures out, and by extension, theories it creates, just add to the writer's creativity. One possible reason earlier movies were more about alien invasions is the fact that humans overestimated the planet's resources. Up until somewhat recently, people thought that we had a great thing going here. Now we see that the planet and its resources are finite, and that we are going to have to leave at some point. Which is why more blockbusters are centered more around space exploration rather than invasions from space. – MikeySheff5 years ago
