Slither

Everything About Fiction You Never Wanted to Know.
It's just a bee-sting...

Slither is a 2006 horror/comedy film written and directed by James Gunn. It is a Homage to gory B-Movie horror films. While not a massive commercial success, the film is something of a Cult Classic.

The plot is essentially, an Alien Invasion film mixed with a Zombie Apocalypse. An alien parasite lands in rural America, infecting and taking control of local man Grant Grant. The alien impregnates a local woman, who gives birth (by having them eat her from the inside out) to thousands of "slugs", that share the original alien's mind. The slugs then enter a person's body through the mouth, killing them. The aliens then take control of the corpse. It's then up to the local police sheriff (played by Nathan Fillion, of Firefly fame), Grant's wife (Elizabeth Banks), the foul-mouthed Mayor, and a local teen to stop the alien before it can infect every living thing on the planet.

Tropes used in Slither include:
  • Action Survivor: Kylie. Over the course of the film, she manages to: grab one of the alien worms as it enters her mouth and pull it out again; burn said worm to death with a curling iron; escape a massive horde of worms by jumping off the roof of her house; take down a couple of worm-zombies (including a zombified deer) more or less by herself; and, ultimately, survive a flying couch to the face with nothing worse than a broken arm. Not bad for a kid with fake nails and a penchant for taking long baths.
  • Alien Invasion
  • Anyone Can Die: And everyone in the whole town but Kylie, Bill, and Starla do.
  • Badass Teacher: Starla. "Bitch is hardcore!"
  • Berserk Button: The mayor isn't exactly a calm guy to begin with, but he really throws a tantrum after he discovers that no one has brought any Mr. Pibb, which is the only soft-drink he likes. This is after everyone's started turning into alien parasite-infected zombies, mind you.
  • Better to Die Than Be Killed: After being turned into a breeder for the parasites, the Mayor begs Pardy to kill him.
  • Big Damn Heroes: Pardy shows up in a big blaze of glory, ready to save Starla, blow up the alien and kick some parasite ass. Subverted, since the alien knocks aside his grenade, it gets dropped in the pool and explodes there, and Pardy promptly gets his ass kicked.
  • Body Horror: Oh so very much of it. Brenda, Grant...
  • Bury Your Gays: Played straight with Margaret.
  • Captain Obvious: "Something's wrong with me."
    • "Um, yeah."
  • Chekhov's Grenade: Subverted. Hard. They make a big deal of showing the viewer the SINGLE grenade that the Sheriff's department owns and the camera lingers on it for a moment. Later, when the hero attempts to use it, it's casually knocked aside and rendered useless.
    • Played straight with Kylie's nails which provide much needed grip during the initial attack.
  • Cluster F-Bomb: The whole film, but especially anything the Mayor says.
  • Crazy Jealous Guy: Grant does not like the idea of other guys getting close to Starla. It's bad enough before he gets possessed by an alien death-worm.
  • Decoy Protagonist: Bill's something like this; the audience is set up to expect him to become the ass-kicking Action Hero when the moment calls, but when the action really kicks off while he's not that incompetent and certainly isn't cowardly, it is pretty clear that he's completely out of his depth, and pretty much every moment that's set up to make him look like a Badass ends with him either running away or getting his ass kicked. He also needs to be rescued more than once by Starla and Kylie.
    • Nathan Fillion certainly confirmed that one of the things he really enjoyed about playing Bill was his bewildered and terrified "what the fuck is going on?!" reaction to almost everything that happened, rather than reacting like a standard Action Hero would.
  • Diagonal Cut: When a single guy tries to stop Grant, the latter casually whips a tentacle at him. He looks, confused, for a few seconds, while blood starts pouring out of a perfectly vertical cut from his head to his groin, before he splits apart.
  • Does This Remind You of Anything?: The scenes where the alien worms possess and impregnate the townsfolk are treated as parallel to rape and sexual assault.
  • The End - or Is It? / Sequel Hook / The Stinger: Keep watching after the end credits.
  • Everybody's Dead, Dave: The entire town is killed except Bill Pardy, Starla and Kylie.
  • Final Girl: Two of them plus a Final Guy. Only Starla completely fills this trope however.
  • Half the Man He Used To Be: A redneck attempting to stop a fully mutated Grant gets bisected by a whip-like tentacle.
  • Hive Mind: The parasite has the mind of every living creature it has ever infected.
  • Hive Queen: Grant.
  • Homage: Most obviously to Night of the Creeps. Starla teaches at Earl Bassett Community School, the mayor's name is R.J. MacReady, there's a store in town called Max Renn's, and Bill mentions the Raglan and Castevet farms. The scene of Kylie getting attacked by a slug in the bathtub has definite echoes of Shivers, as well.
  • Horror Hunger
  • I'm a Humanitarian: Those turned into breeders want meat. Any meat...
  • Infant Immortality: Averted with the creepy cannibal Undead Children.
  • Omnicidal Maniac
