Year One (2009) is a prehistoric comedy adventure directed by Harold Ramis, starring Jack Black and Michael Cera as Zed and Oh, two incompetent hunter-gatherers exiled from their primitive tribe. Their journey through the ancient world becomes a hilarious tour of Biblical antiquity as they accidentally cross paths with figures like Cain and Abel, Abraham, and Isaac, eventually finding themselves in the notoriously sinful city of Sodom. The film blends slapstick humor with satirical takes on well-known religious stories, creating a unique and often absurd comedic landscape.

Jack Black delivers his signature boisterous energy as the ambitious but clueless Zed, while Michael Cera provides perfect deadpan contrast as the meek and logical Oh. Their chemistry drives the film, with the script playing to their contrasting comedic strengths. Director Harold Ramis, known for classics like Ghostbusters, brings a lighthearted, episodic structure to the journey, though the film's reception was mixed, with some critics finding the humor uneven.

Despite its modest IMDb rating, Year One offers a specific brand of humor for fans of its lead actors and absurdist historical comedy. The premise allows for countless gags about the dawn of civilization, from the invention of fire to the social customs of ancient cities. If you enjoy comedies that play fast and loose with history and mythology, or are simply a fan of Jack Black and Michael Cera's comedic pairing, Year One is a breezy, 97-minute film worth watching for its sheer silly ambition and occasional laugh-out-loud moments.
