Two neolithic losers stumble into Old Testament-era civilization. Patchy lowbrow comedy ticking off every genitals-related gag in the scrolls. Some funny moments; the always-welcome Oliver Platt steals the show as a lascivious high priest.
Attempts to create a serum to reanimate the dead go predictably awry. Flatliners meets Lucy in this by-the-numbers lab-bound horror/thriller in which a decent cast try their best to get through a rote script.
