Year One (2009), directed by Harold Ramis, is a prehistoric buddy comedy that follows two inept hunter-gatherers, Zed (Jack Black) and Oh (Michael Cera), after they are exiled from their primitive tribe. Their journey through the ancient world leads them to stumble upon famous Biblical characters and stories, including Cain and Abel, Abraham and Isaac, and ultimately the decadent city of Sodom. The film blends slapstick humor with satirical takes on religious tales, positioning its modern comedic sensibilities against an ancient backdrop.

Jack Black delivers his signature boisterous performance as the overconfident Zed, while Michael Cera provides perfect deadpan contrast as the meek and neurotic Oh. Their chemistry drives the film's humor, playing off familiar anachronisms and fish-out-of-water scenarios. The supporting cast, including Oliver Platt, David Cross, and Hank Azaria, adds to the comedic ensemble with memorable cameos.

While Year One received mixed reviews from critics, it has developed a cult following among fans of absurdist humor and the lead actors' styles. The film's premise allows for creative anachronistic jokes and lighthearted parody of epic Biblical narratives. At 97 minutes, it's a brisk, undemanding comedy that doesn't take itself seriously. Viewers should watch Year One for its unique comedic concept, the entertaining dynamic between Black and Cera, and its playful approach to historical and religious satire. It's particularly enjoyable for fans of buddy comedies seeking something different from conventional settings.
