It’s called “Arrival.” Not “Attack” or “War of the Worlds.” In this thought-provoking, conceptually ambitious film, the creatures from another world just…arrive. At twelve points around the globe, huge, monolithic spacecraft that look like flying saucers turned sideways are suddenly just there. What do you do? How do you determine the intentions and capacities for harm from a species of creature with whom you do not have the most fundamental experiences and assumptions in common? Do they even have a language we are capable of understanding? Do they have the capacity to speak or write? Do we have the capacity to understand? Is this “ET” or “Battlefield Earth?” Or maybe that “Twilight Zone” episode where the book the aliens bring titled To Serve Man turns out to be a cookbook?

And how can we tell? This is not one of those sci-fi movies where the aliens get some TV signals and teach themselves English by watching game shows and sitcoms. So, the US military seeks out a linguist (Amy Adams as Dr. Louise Banks) because before we can decide what our response will be, we have to try to find a way to figure out how to communicate with them. “Language is the foundation of civilization,” she says to another expert being transported to the alien ship with her. “No,” he tells her. “It is science.” He is a physicist (Jeremy Renner as Dr. Ian Donnelly). If you think that both sets of skills will be necessary, that they will find a way to communicate, and find some connection with one another as well, you are right, but it will still surprise you all the way to the end.

Director Denis Villeneuve is not afraid to take on big issues and complex questions. And, as always in movies about aliens, it is more about who we are than who they are. Positioning us against creatures who are completely unknown requires us to think more deeply about our assumptions and capabilities.

Louise figures out a way to begin to communicate with the floating squid-like creatures. But is the word they are conveying “tool” or “weapon?” And will humans around the world be able to find a way to work together or will one country undermine our efforts to communicate by attacking the alien ships? We may be better at communicating with other species than our own.

The details really matter here and production designer Patrice Vermette fills the screen with thoughtful, illuminating touches from the Brancusi-like sculptural curves of the spacecraft to the calligraphy-like symbols created by the aliens. Striking images inspire awe and wonder in us as they do the characters. And the Chomsky-esque notions that language shapes our thinking even more than our thinking shapes language is conveyed in the film’s own structure as well as its dialog. Ultimately, it is a reminder of the power of communication, with movies themselves as one of humanity’s best examples.

Parents should know that this movie’s theme includes worldwide threats, with some peril, very sad illness and death of a child, divorce, and some strong language.

Family discussion: Which is the foundation of civilization, language or science? Or is it something else? What would you ask the aliens?
