In Warm Bodies, Julie Grigio (Teresa Palmer) is sent out from the zombie fort to find medical supplies. She’s promptly surrounded by zombies, but one of them named R rescues her. They gradually develop a love for each other, which makes R transform from the undead to the living. It’s just like in the old fairy tales.
In Warm Bodies, R (Nicholas Hoult) is not your typical zombie. He is able to communicate, granted with grunts and moans. He gets enjoyment from eating food, granted by devouring human brains and experiencing their memories. And he falls in love with the non-zombie Julie Grigio, granted after consuming her boyfriend.
