Zombies (Zombieland)

In the r rated zombie comedy Zombieland there is a very unique type of zombies. These zombies are said to have started out as normal people, until a man (who the movie's main character, Columbus refers to has "patient zero") ate a contaminated hamburger at a resturant/gas station called "Gas n Gulp", made out of meat from cattle with the most advanced cases of mad cow desease. The "mad cow burger" infected the man and mutated the desease into "mad zombie desease", a desease which gives the victim a raging fever, a swollen brain, green skin, takes away their speech ability, and makes them into canniballs while turning their blood black. The desease spreads across America and infects almost everyone in just two monthes, leaving only a few people left alive to fend for themselves. The movie follows Columbus and his friends as they try to survive the zombies while also trying to find a way to "enjoy the little things" left in the now zombie infested America. Unlike how zombies are usually shown, these zombies are very fast, it is also worth noting that they are really not undead since they are merrly humans infected with a desease, hinch these zombies can actually be sympathised with. Unlike most zombie movies, here there are clarly both males and female zombies (one of which is named 406).
