Watch The Rock befriend gorillas and fight flying wolves in Rampage

The Rock is starring in a monster movie loosely based off of a video game series, which is just about the most The Rock thing The Rock could do. In the latest trailer for Rampage, the man now known as Dwayne Johnson rocks out with a big ol’ friendly gorilla who — after being infected with an interstellar mutation — is swept up into a city-leveling conflict.

An adaptation of Rampage has been in the works since 2011. The Midway game series lets you control a giant lizard, ape, or wolf as you destroy a city and fight off helicopters and their guns. Honestly, Rampage doesn’t have a whole lot of plot to base a movie on, which is probably why the trailer’s leap from “The Rock has a signing gorilla friend” to “Oh hey, flying wolves” doesn’t quite work. But perhaps the film’s official description can help:

Primatologist Davis Okoye (Johnson), a man who keeps people at a distance, shares an unshakable bond with George, the extraordinarily intelligent, silverback gorilla who has been in his care since birth. But a rogue genetic experiment gone awry mutates this gentle ape into a raging creature of enormous size. To make matters worse, it’s soon discovered there are other similarly altered animals. As these newly created alpha predators tear across North America, destroying everything in their path, Okoye teams with a discredited genetic engineer to secure an antidote, fighting his way through an ever-changing battlefield, not only to halt a global catastrophe but to save the fearsome creature that was once his friend.

Okay, maybe going to the description was a bad idea. Rampage arrives in theaters on April 20th. Hopefully it’s better than the Doom adaptation.
