Get ready to Rampage on April 20, 2018.

Dwayne “The Rock” Johnson re-teams with San Andreas director Brad Peyton for Rampage, an adaptation of the same-named arcade game from 1986. In the film, a genetic experiment gone wrong transforms ordinary animals into massive, raging monsters, and we’ve got your first look at one of those monsters tonight.

Ahead of tomorrow’s trailer, Johnson took to Twitter to share the official poster for Rampage, tweeting “This is my best friend, George. A rare gigantic albino Silverback. I love animals because they’re honest. If they like you, they lick you. If they don’t, they eat you.”

“Our #RAMPAGEMovie trailer drops TOMORROW at 5PM EST/2PM PST,” he added.

Check out the poster below!

In the film, “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 transforms this gentle ape into a raging monster. To make matters worse, it’s soon discovered there are other similarly altered alpha predators. As these newly created monsters 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.”

The screenplay is by Ryan Engle and Adam Sztykiel, story by Ryan Engle.
