‘The Wild Robot’ Review: Wonder and Whimsy That Does Compute

Have you ever thought about the many ways animals show emotion? Consider an inquisitive snout wriggling in the air, tails coiled protectively around cubs and ears perky or drooping depending on mood. For creatures who didn’t evolve to walk upright, wearing one’s heart on one’s sleeve is a considerably more anatomical business.

Among the achievements of “The Wild Robot” is a painstaking regard for details like these. Written and directed by Chris Sanders (“How to Train Your Dragon”) and adapted from Peter Brown’s novel, the movie is a dazzling triumph of animation in which you feel the filmmakers’ attention on every frame. In a revivifying turn away from the gag-a-minute, computer-generated extravaganzas clogging up the animated zoological canon, this is a work that cares most about two things: big feelings and great beauty.

That’s not to say that its machine is built entirely of new parts. In some ways, this kid-friendly affair about an interspecies found family even leans into its derivative elements. Roz, the bionic hero of “The Wild Robot,” seems designed to evoke the title character in “The Iron Giant,” sharing that monster’s studying eyes and lanky stature. But rather than outer space, she hails from today’s sinister science-fiction analog: the conglomerate Universal Dynamics, which specializes in robotic digital assistants. Think Alexa in hulking metal form.

The movie begins as Roz (short for Rozzum Unit 7134) accidentally washes off a cargo ship and ashore a wildlife island, where she swiftly begins scouting for a task that satisfies her serve-at-all-costs programming. After wreaking havoc on some fauna, the robotic assistant (voiced by Lupita Nyong’o) stumbles upon a purpose: raising an orphaned, newborn gosling whose kin she accidentally squashed.

Brightbill, as she names him, is on the runty side, and although Roz grows more sociable — at first, she can speak only in Robotese, which is so stilted it might as well be Middle English — her ward (voiced by Kit Connor, of the Netflix series “Heartstopper”) struggles to master the basics of his pond and sky habitats. Tagging along for the child-rearing is a rascally fox named Fink (Pedro Pascal), who alternates between parenting advice and snide remarks. The impending winter imposes a ticking clock on Brightbill’s training: Should he fail to become airborne before migration time, he will perish in the cold, assuming he’s not eaten first.
