He's sassier than C-3PO and doesn't take kindly to instructions. Of the many highlights in "Rogue One: A Star Wars Story," the movie finds its showstopper in the opinionated droid K-2SO (performed in motion capture by Alan Tudyk). Read on to see more of our 2016 scene stealers:
Jenny Slate's lovestruck Pomeranian named Gidget in "The Secret Life of Pets" won major points for devotion and just being plain adorable.

Speaking of Keanu, the kitten portrayed in the Keegan-Michael Key and Jordan Peele springtime comedy of the same name stole the show. All of his little outfits in "Keanu," not to mention the kitten calendar sequence during the end credits are enough to make moviegoers meow with approval.

Mr. Big (voiced by Maurice LaMarche) is unforgettable in "Zootopia" as a gangster kingpin with a Joe Pesci-esque delivery.
Fans' first look at Tom Holland's Spider-Man was in "Captain America: Civil War." Even though he was on screen for a few short minutes, he showed himself to be simultaneously charming and acrobatic during his debut.
Channing Tatum sang and danced his way through a memorable supporting role as a 1950s era big screen star in the Coen Brothers' comedy "Hail Caesar!"
Sigourney Weaver plays herself in "Finding Dory," as the celebrity voice that guides guests through the state-of-the-art aquarium from where the forgetful Blue Tang fish must escape.
Arguably one of the most egregiously under-watched movies of the year, the lovely "Love & Friendship" features a very funny Tom Bennett as a man who comes courting Kate Beckinsale. We dare you not to laugh as he attempts to dance.
Remember the seagull from "The Shallows"? If you've seen the movie your answer would be a resounding "hell yes."
The super slow sloth at the DMV in "Zootopia" put real-life workers at the government agency to shame.
An apparent spoof of Donatella Versace, Kristen Wiig played for laughs as a lip-plumped fashion designer with an indecipherable accent in "Zoolander 2."
Sometimes being a scene stealer is a dubious distinction. Such were a handful of Japanese soldiers depicted in the Mel Gibson-directed World War II drama "Hacksaw Ridge." The enemy fighters pop up on screen quite quickly, scaring the bejeezus out of conscientious objector Desmond Doss, played by Andrew Garfield. They also elicit a horror movie-style jump scare from the audience -- hardly a positive attribute from an awards season contender.
"Fantastic Beasts and Where to Find Them" shined that much more brightly when Alison Sudol appeared in the film as the mind-reading Queenie Goldstein.
Chris Hemsworth is a manly, yet, dim-witted assistant who also serves as great eye candy for the ladies in "Ghosbusters." His enthusiastic dance moves during the end credits alone are worth the price of admission.
There is a huge NASA-made motion visualization of the Earth's climate featured in the documentary "Before the Flood." And yes, it is arguably the movie's biggest scene stealer. Scientist Piers Sellers uses it to show Leonardo DiCaprio ocean surface temperatures as measured from space -- and points out that it captures the poles melting.
