I think it says a lot about me when the first fifteen horror movies I can come up with include a lot of hybrids—a couple of thriller crime/horror hybrids, a bunch of SF/horror hybrids, and a pair of comedy/horror hybrids. Like this one.
“You’ve got red on you.”
Shaun of the Dead isn’t a true horror movie; it’s a romantic comedy, but one that stays within the constraints of a zombie movie. Simon Pegg is an office zombie, going through his day to day life, hanging out with his slacker friend (Nick Frost) and trying to win back his girlfriend (Kate Ashfield), which just so happens to occur during a zombie apocalypse. That’s where a lot of the humor comes from: Pegg’s Shaun doesn’t even notice the zombies at first, too caught up in his thoughts.
The fact that it’s also a checklist for zombie film components is also a plus: escape scenes, gruesome walking dead, the slow and eventual deaths of the less-important group members, one group member getting bit, the climactic hold-0ut scene… it’s all there. Only neatly subverted into comedy: instead of holding out in an office building or mall, they hold out in a pub; the person who’s infected by the zombies is Shaun’s girlfriend’s mother; the escape scene involves the survivors zombie-walking through a group of undead.
Why is it scary?
It’s not; not in the slightest bit. It is, however, pretty funny, and the zombie special effects are terrific. As a horror rom-com hybrid, I think it does what it set out to do damn well: be a comedy movie set within the boundaries of a zombie film. All the classic zombie film bits are there, making it an authentic zombie film, which it uses to its advantage: the movie takes a serious-but-comedic approach to panning the genre.
I think it holds up a lot better than the other serious zombie comedy (zom-com?), Zombieland, which had a lot going for it but was too short and too shallow and was largely powered by hype. Shaun came out of left field—being British helped, nobody in the States pays any attention to foreign films being developed, which is a shame—and I think being a pleasant surprise, with its distinctly British wry humor, made the film stick out in my mind.
At the end of the day, it may not be a real horror film, but it is one of the best zombie movies ever made.
