Over the course of humanity, different ideas of what extraterrestrial life might look like have come and gone, and some have stuck. Whether it’s the greys, reptilian lifeforms, human-looking, microbial, or straight up nightmarish Killer Klowns from Outer Space, our universe is said to be flooded with a variety of species. This is no different in the landscape of aliens on film, which have graced our screens.
