Sure, movies can be copyrighted, but did you know monsters can, too? And even a particular version of a monster? Zombies were around before George Romero's 1968 movie Night of the Living Dead, but he put his own spin on the idea. His version -shuffling corpses that menace humans in order to eat their flesh- became the zombies we see in movies like 28 Days Later, World War Z, and Zombieland, and TV shows like Z Nation and The Walking Dead. It all has to do with copyright.
