Shaun of the Dead was released in 2004, referring to itself as romantic zombie comedy (aka rom zom com). A satirical look at the zombie genre, made popular by films like Night of the Living Dead and its sequel Dawn of the Dead, Shaun of the Dead stars Simon Pegg and Nick Frost as Shaun and Ed trying to survive in a world quickly being taken over by zombies. Unlike other zombie movies, this film is much more of a comedy than a horror, and was initially inspired by an episode of the Brittish sitcom Spaced in which Simon Pegg's character, while under the influence of amphetamines imagines that he is fighting zombies.
