Also producing the film is Judd Apatow, director-writer-producer of "Knocked Up," which bowed in last weekend at No. 2 at the U.S. box office, Variety reported Monday.
Michael Cera, who stars in "Superbad," another Apatow production for Columbia, is also slated to be in "Year One."
Ramis also co-wrote the project, based on his story, with "The Office" writers Gene Stupnitsky and Lee Eisenberg.
