GoKawiilThe film adaptation of Andy Weir’s novel Project Hail Mary hits general release today, March 20, and it’s great—go see it! Though a little light on the science, the movie goes hard on the relationship between schoolteacher Ryland Grace (Ryan Gosling) and an extraterrestrial named Rocky, and it’s a ride well worth taking.
But as good as it is, the movie shares a small flaw with the book: Despite having very few things in common, Grace and Rocky learn to communicate with each other extremely quickly. In fact, Grace and Rocky begin conversing in abstracts (concepts like “I like this” and “friendship”) in even less time than it takes in the book. Obviously, there are practical narrative reasons for this choice—you can’t have a good buddy movie if your buddies can’t talk to each other. It’s therefore critical to the flow of the story to get that talking happening as soon as possible, but it can still be a little jarring for the technically minded viewer who was hoping for the acquisition of language to be treated with a little more complexity.
And because this is Ars Technica, we’re doing the same thing we did when the book came out: talking with Dr. Betty Birner, a former professor of linguistics at NIU (now retired), to pick her brain about cognition, pragmatics, cooperation, and what it would actually ake for two divergently evolved sapient beings not just to gesture and pantomime but to truly communicate. And this time, we’ll hear from Andy Weir, too. So buckle up, dear readers—things are gonna get nerdy.
A word about spoilers
This article assumes you’ve read Weir’s novel and that you’ve seen the movie. However, for folks who haven’t yet seen the film, I don’t think there’s much to be spoiled in terms of the language acquisition portions that we’re going to discuss—the film covers rather the same ground as the book but in a much more abbreviated way.
