“It was more just a feeling of being very tired and heavy,” Hoult said. “He hasn't got to be anywhere.”
While Hoult and co-star Rob Corddry worked with a trainer from Cirque du Soleil to perfect the physicality of reanimated corpses, Palmer aimed to give her character, Julie, the strength it would take to survive in an embattled dystopia.
“She's a strong, feisty woman who can shoot a gun and take care of herself,” Palmer said. “I think I would be pretty good in that kind of world, I have to say. Because of all the training on ‘I Am Number Four' ... and knowing how to shoot a shotgun because of ‘Warm Bodies,' I think I'd fare pretty good in a zombie apocalypse.”
But while Palmer toughened up for “Warm Bodies,” she did not face the unique culinary difficulties encountered by her co-star. As part of his performance, Hoult had to consume a concoction made to look like human brains.
“It was a wet and cold thing with blood on top and some grapefruit occasionally, and bits of random stuff,” Hoult said. “It was like a peachy sponge.”
