''Year One'' is a 2009 comedy starring Creator/JackBlack and Michael Cera as a pair of weak hunter-gatherers in AncientRome who get caught up in a plot to rescue their tribe from the City of Sodom.
Zed (Black) and Oh (Cera) are would-be hunters who dream of becoming something more. After the duo are banished from their tribe (thanks to Zed eating from a tree of ForbiddenFruit), they embark upon a series of adventures, and run into various characters from Literature/TheBible ([[BeenThereShapedHistory influencing historical events as a result]]). The two are eventually captured and brought as slaves to the City of Sodom, where they discover the women they once pined for, Maya and Eema, have also been enslaved, along with the rest of their tribe. It's up to Zed and Oh to rescue their tribe and become the heroes they were meant to be.
The film features a large amount of AnachronismStew and features a wide assortment of noted comedic actors in bit parts. Not to be confused with ''ComicBook/BatmanYearOne.''
!!This movie provides examples of:
* ArsonMurderAndJaywalking: If it ends in an "ee" sound chances are Zed and Oh were accused of it.
* Literature/TheBible: Abraham and his sons, Cain and Abel.
* BigBrotherInstinct: Eema and Zed were siblings. Later in the film, Zed saves Eema from a Roman commander.
* BrickJoke: Cain killing Abel. Even though no one save for Oh, Zed and Adam really cares, any mention of the mark on his forehead causes him to deny the murder.
* BrotherSisterIncest: Averted - Zed says he feels no attraction to Eema, to which Oh reminds him that she's his sister.
* ButtMonkey: Oh.
* CainAndAbel: Cain is arrogant and psychopathic, as he is portrayed in most modern works. He even gets a lightning bolt to the head.
* ClapYourHandsIfYouBelieve: After Zed teaches people to clap, [[spoiler:it starts raining]]. From that point forward, the rain begins whenever people clap and stops when they stop clapping.
-->'''Oh:''' 'Y-You were holding a rock and he ran into it with his face repeatedly until he couldn't pull through!'
* TheChosenOne: Zed, who plays it up to the end until [[spoiler:he says he's not]].
* EatMyDust: What Cain says to his father as he's fleeing on a slow-moving camel.
* ForbiddenFruit: Zed eats golden apples that are forbidden, and a snake wraps around Oh. The fruit doesn't actually do anything though.
* GrossoutShow: This movie has lots of disgusting scenes.
** Case in point: the oil rub scene...
** And poor Oh urinating on his own face while he's hanging upside down in prison.
-->"I'm not a slave, I'm a volunteer."
* HasTwoThumbsAnd: "Who has two thumbs and wants another hot oil rub?"
* LethallyStupid: Zed.
-->[[RunningGag ''What's going on behind you?'']]
* MadeASlave: Most of the original village. Oh and Zed were able to run into the desert.
* MistakenForGay: Oh is usually worried that Eema thinks this about him, and the eunuch thinks he is too.
* PottyFailure: In the scene where Zed and Oh are chained up in the dungeon, Oh (chained upside down) yells that he has to pee, and then he ''pees all over his face''.
-->Cain: I wish you were dead too! Even though Abel is not dead at all!
* TakeMeInstead!: When Eema is going to be sacrificed.
-->'''Oh:''' [[RunningGag Why all the genital mutilation?]]
--> '''Oh:''' ''[gets whipped]'' Like to see how big you are without that whip!
--> '''Slave Driver:''' [Drops whip, and raises arms in a BringIt gesture]
--> '''Oh:''' [beat] [[OhCrap Same basic size.]]
-->'''Oh:''' Seems like a waste of a perfectly good virgin to me.
