Primatologist Davis Okoye 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.
This movie contains 19 potentially triggering events.
A Golden Retriever is shown barking at a large mutated wolf. The wolf growls at the dog, the dog whimpers and runs away. The dog is not harmed in any way.
Not specifically 9/11, however there are some very similar images. Planes crash into skyscrapers and a skyscraper collapses with a large clowd of debris.
Amputation is mentioned and shown in an indirect way - they show poachers hacking at a gorilla’s body (mentioning that they cut her hands off) but this is not shown graphically
At the very beginning of the film, a mutated rat is onboard a space station. A very clear view of the animal is never shown, but the space station is evacuated and explodes with the animal still inside. The animal actually dying/exploding is never shown, just the station exploding from a distance.
Throughout the film, we also see: a dead Grizzly bear shown bloody in his enclosure, a field of slaughtered wolves shown through video footage, the shooting of a mutated wolf, the same mutated wolf being decapitated by the mutated crocodile, and the mutated crocodile dying after being impaled by George. George is injured several times throughout the film and appears to have succumbed to his injuries after the fight with the crocodile, but he's playing opossum. ;)
One of the character's backstories is that she was trying to save her brother from cancer. We see him briefly in a photo looking very ill, but never meet him, as he's dead before the movie starts.
