The latest trailer has arrived for Rampage, and it's full of revelations (some would say spoilers) about Dwayne Johnson's next big-budget action film.

We already knew that the film's giant gorilla (George), alligator and wolf will find themselves altered after being exposed to a gene-splicing chemical agent. However, the new trailer reveals that Naomie Harris' character, Dr. Kate Caldwell, is at least partially responsible for the creatures' massive growth spurts. Further, the transformation includes at least one secondary mutation to go along with the giant growth, in the case of the wolf at least; the giant animal also grows wings, much to the Rock's chagrin.

Rampage is an adaption of the beloved ’80s arcade game that allowed players to choose between three different characters: a giant ape, a giant lizard and a giant werewolf, all of which were human prior to a freak lab accident.

Debuting April 20, 2018, Rampage stars Dwayne Johnson, Naomie Harris, Malin Ackerman, Joe Mangianello, Jake Lacey, PJ Byrne, Mary Shelton, and Jack Quaid. The film was directed by Brad Peyton (San Andreas) from a script by Ryan Condal and Carlton Cuse, based on a story by Ryan Engle.
