Warm Bodies

About eight years after a zombie apocalypse, R, a zombie who cannot recall his name but believes it began with an "R", spends his days wandering around an airport which is now filled with his fellow undead, including his best friend M. R and M achieve rudimentary communication with grunts and moans and occasional near-words. As a zombie, R does not have a heartbeat and constantly craves human flesh, especially brains, as he is able to "feel alive" through experiencing the victims' memories when he eats them.
