What's a zombie animal movie without an all-star cast of, well, animals?
Zoombies director Glenn Miller, who calls working on set with real animals "insane," gives viewers a behind-the-scenes look at his main wildlife stars. In addition to badass monkeys, the film features gorgeous parrots, fierce lions, and even a dude in a gorilla suit.
"[Monkeys] carry the full spectrum of emotions that we do. What makes it possible to work with a complex animal like this, an intelligent animal, is relationship," says trainer Jeffrey Lee. "It's that mutual trust and respect that makes it possible for us to be able to take them on film sets and work around actors and film producers."
