Feast

Feast is a horror trilogy that is a result of the first film being a part of the third season of the Project Greenlight contest. The winning team was composed of writers Marcus Dunstan and Patrick Melton and director John Gulager. It was executive produced by Ben Affleck, Matt Damon, Chris Moore (through their Live Planet production company), Wes Craven and the Maloof family. John Gulager would go on and take control over the film series.

The series is notable for setting itself up and marketing itself as a parodic comedy, then taking a turn for the horrifying.

Feast

In a remote bar, customers are advised by a newcomer to seal the place since hungry monsters will attack them in a couple of minutes. Due to the events that happen immediately after this warning, the clients organize a strategy to defend the place under siege of deadly monsters.

Throughout the film, almost none of the characters refer to each other by their actual names. They are each identified to the audience by a nickname when he or she first speaks or otherwise becomes the focus of attention. This is accomplished by momentarily freezing the current frame to display the nickname as well as other helpful information, such as their chance of survival.

Feast 2: Sloppy Seconds

The film is set in a nearby town immediately after the events of the first film. The monsters have made it into a small neighboring town in the middle of nowhere and the locals have to band with the survivors of the bar slaughter to figure out how to survive.

Feast III: The Happy Finish

Picking up moments after the end of Feast 2: Sloppy Seconds, Honey Pie is killed by a creature and the other survivors are saved by the mysterious prophet, Short Bus Gus, who seemingly has the ability to control the monsters. He leads them into the sewers as they travel to the big city. Along the way they get help from karate expert Jean-Claude Seagal and learn that the monsters originate from a place called the Hive. Armed with this knowledge, they decide to fight back and destroy the monsters once and for all

Tropes used in Feast include:

Action Girl: Herione and Tuffy (a.k.a. "Herione 2") in the first movie, Biker Queen and her gang in later installments.
Anyone Can Die
Badass: Pretty much everyone who lasts more than half a movie ends up this way. On the other hand, declaring yourself a badass guarantees that your life expectancy can be measured in minutes.
Badass Biker: Biker Queen, and pretty much her whole gang.
- Subverted with Harley Mom, who lived only long enough to lose a limb and get orally raped.
Badass Grandpa: Bartender. Probably because he's played by the director's dad.
Black Dude Dies First: Slasher lampshades this in the third movie.
Body Horror: The monsters' internal organs are another monster swimming a variety of nasty juices. Getting too much monster juice on (or in) a person turns them into a lunatic, a rotting corpse, or another monster, depending on the level and method of exposure.
Bring My Brown Pants: Tit Girl, Tat Girl, and Biker Queen kick the shit out of Hobo. Literally.
Dead Baby Comedy
Death by Looking Up: Secrets and Lightning at the end of Feast III.
Death By Pragmatism: Played with, but mostly averted. Characters die pretty much no matter what they do, but ruthless pragmatism (such as sacrificing their allies, leaving others for dead, and using live babies as bait) helps them live a lot longer.
Decoy Protagonist: Hero sounds like the perfect name for a protagonist. He's the very first person to die. And then we have Shitkicker from the third film, who looks just as badass as Hero, and even teaches Secrets how to use a gun. And then she shoots him under the chin.
Exactly What It Says on the Tin: The second and third films include a character named "Tit Girl." Take a wild guess what her primary characterization is.
Eye Scream: Beer Guy has an eye pulled out of its socket in the first film. Later, in Feast III, Tit Girl has both of her eyes gouged out. That's not even how she dies...
Face Full of Alien Wingwong: Slasher. Almost with Bozo, but averted when part of it gets cut off by Heroine after it gets caught in a closing door. Played straight with Harley Mom, shortly before she is blown up.
Fatal Family Photo: For all the times that Heroine talks about her daughter Charlie waiting for her, it's a wonder she survived as long as she did. She might as well have been two days from retirement, too.
Gag Penis: Subverted; Lightning's penis reaches down to his kneecaps. Which would be a lot more impressive if not for the size of the rest of his body.
Gainax Ending: The third movie ends with Lightning and Secrets getting crushed by a giant robot. Then a mariachi player shows up to sing a recap of the trilogy, which may or may not actually be concluded with Feast 4.
Gorn
Half-Human Hybrid: Slasher/Hybrid
Half the Man He Used To Be: Thunder in Feast II, Jean-Claude Seagal in Feast III.
Impaled with Extreme Prejudice: Boss Man and Greg Swank. Inverted in the latter case, as he survives a pipe through the head but dies when it's removed.
Infant Immortality: Brutally and shockingly subverted. Twice.
Killed Mid-Sentence: Hero dies halfway through introducing himself.
Kill'Em All: The final(?) installment of the series goes out of its way to do just that. Except Bartender.
Losing Your Head: Hero and Honey Pie.
Not Quite Dead: Used twice in the first film - Harley Mom has her legs ripped off and is presumed dead, until Bozo and Bossman discover she is alive when they try to use her body as bait. They still do it. Beer Guy has his eye ripped out, but gets up a few minutes later and manages to survive for another good chunk of the film.
Refuge in Audacity: And how!
Senseless Sacrifice: Jean-Claude Seagal. He dies within seconds, and all of the characters (except Bartender) end up dying anyway.
Shout-Out: Martial artist Jean-Claude Seagal.
- Tuffy shouts 'Choke on it!' as she's literally choking one of the creatures to death with her own fist, having just smashed all of its teeth out with the butt of an empty shotgun.
Sudden Sequel Death Syndrome: Honey Pie and Thunder in Feast III.
Teeth Flying: In the climax, the second Heroine uses a rifle butt to knock out every last one of a monster's many, many teeth. Then tops this by shoving her arm through its now-harmless jaws, and all the way down its throat, so it chokes to death!
There Is No Kill Like Overkill: Puker Girl stabs Tat Girl over thirty times, even though she was probably dead after the fifth stab. Biker Queen later avenges her death by tackling Puker Girl down, and pulling her intestines out of her vagina.

Biker Queen: "That's how you gut a bitch, bitch!"

Took a Level in Badass: Tuffy, whose name changes to Heroine 2.
- At the end of Feast III, the remaining survivors tackle Slasher/Hybrid to the ground and mutilate him using nothing but their teeth.
The Virus
Toilet Humour : Not so much in the first, a scene the autopsy entirely dedicated to it in the second, and the third basically opens with it.
Vasquez Always Dies: Harley Mom.
What Happened to the Mouse??: Where did Tuffy/Heroine 2, Bozo and Hot Wheels end up after the first film?
