You should watch The Rock's challenge video below for the Kevin Hart/cat insult alone.

In "Rampage," an adaptation of the 1980s video game, Dwayne Johnson plays Davis Okoye, a primatologist whose best friend is a 7-foot-tall, 500-pound rare albino silverback gorilla named George. Naomie Harris costars as genetic scientist Dr. Kate Caldwell, with Jeffrey Dean Morgan as government agent Harvey Russell, and Malin Akerman as the villainous Claire Wyden.

USA Today shared the first two photos from the movie, with the first trailer arriving this Thursday, Nov. 16. "Rampage" follows an experimental serum gone wrong, leaving George and other creatures growing enormous and going on a path of destruction.

Here are Dwayne Johnson and Naomie Harris in action:
