"Year One" is about two prehistoric hunter-gatherers, named Zed and Oh, who are banished from their tribe after Zed eats forbidden fruit from the Tree of Knowledge of Good and Evil. After Zed burns down their village, the two men go on a journey to discover the world, and they encounter various Biblical characters along the way.
Among the characters Zed and Oh meet are feuding brothers Cain and Abel, played by David Cross and Paul Rudd, respectively; Abraham and his son Isaac, played by Hank Azaria and Christopher Mintz-Plasse; and the princess Inanna, played by Olivia Wilde. The film culminates in Zed and Oh's arrival at Sodom and the trouble they stir up after being captured there.
"Year One" was the last film Harold Ramis directed, wrote and starred in. The cast of the film includes Jack Black as Zed and Michael Cera as Oh. Columbia Pictures released the film in the summer of 2009, and it became a box office disappointment when it only grossed $43 million in the United States. Critics reviewed the film mostly negatively upon its release, maligning it for being poorly executed and relying on sophomoric humor. Roger Ebert awarded it one star out of four, calling it a dreary experience.
