All these influences led to the kind of zombies moviegoers saw in 28 Days Later.
Danny Boyle added that another source of inspiration for 28 Days Later zombies also came from retired athletes and gymnasts who were hired for corporate jobs, noting how if one of those individuals was charging straight at you, there was nothing you could do.
Granted, that’s the same case in other zombie movies and television shows, but at least with them, there’s no need to worry about the zombies running like a track star or having ridiculous muscles.
