"Four limbs, one head, two eyes... Most aliens in cinema are distant cousins of ours. But, breaking away from this common ground, there are films at two opposite ends, perhaps those that best use the infiltration of otherness from beyond space to better point out the strangeness here among the terrestrials.
On one hand, we have films that present the alien as 'he is among us', with a human appearance, which nonetheless does not disguise their strangeness.
Other works have chosen to make this 'other from space' invisible, to the point of situating it beyond all communication.

In the first group are "Invasion of the Body Snatchers," presented here in its original 1956 version by Don Siegel, and already from this century, "Under the Skin," by Jonathan Glazer (2013).

Don Siegel's film proposes to us a hybrid plant, between animal and vegetable, with the capacity for reproduction, but not of itself. In an environment that inherits from the detective film, or noir, when sci-fi was still constructing itself as a genre, nothing is as it seems in "Invasion of the Body Snatchers." The ambiguity of the narrative grows in emotional tension – in contrast with the invaders – until it leaves us in limbo between paranoia and conspiratorial infiltration. The replacement of humans here is a powerful metaphor, with various meanings and so relevant in the 21st century.

In "Under the Skin," Jonathan Glazer, the 'other' alien, embodies a human woman (beautiful, perhaps, in the form of Scarlett Johansson) who slowly experiences our human condition and who throughout the film will question herself about our capacity for empathy and her initial attitude as a predator who takes advantage of human emotions.

"The Andromeda Strain" (1971) presents us with another hybrid – a microscopic extraterrestrial with a mineral structure. Without face or soul, it is against this space virus that another organism is built, on another scale: the coordinated collective effort of a complex scientific collaboration. With a script from the same author as "Jurassic Park" and special effects from the same designer as "2001: A Space Odyssey," this other major production is full of action, but of an unusual kind: in a race against time, teams of scientists in a high-tech laboratory conduct parallel experiments, cross data, launch hypotheses, and discuss from various angles the strange mortal life form that appears under their microscope.

In an exercise of looking at the 'other' in these film screenings, we offer here an increase in amplitude, since this contact may even be brief to occur.
