We prefer our caveman movies to feature Raquel Welch in tiny bikinis, but if concessions need be made, they could be a lot worse than Jack Black and Superbad’s Michael Cera as hapless hunter-gatherers.

The Judd Apatow–produced script, cowritten by director Harold Ramis and the folks behind The Office, digs deep into a fossil-rich shale of funny, with David Cross and Paul Rudd as a hilarious Cain and Abel who bicker (what else?) endlessly.
