While preparing for his role in Warm Bodies, Hoult went as Method as he could for the part by learning how to behave like a zombie. Hoult and co-star Rob Corddry attended movement classes under the supervision of a former member of Cirque du Soleil. "We’d kind of grow out of the wall and make our bodies feel very heavy. It was good," Hoult said in a recent interview. It was one of those things where you think about it a lot but you’ve just got to try it out and see what works."
