Cavemen (2007)

Joel, his cynical best friend, Nick, and easy-going little brother, Jamie, are contemporary cavemen who live in the suburban south and simply want to be treated like ordinary thirty-something guys. Despite their attempts at assimilation, Nick doesn't believe mainstream society will ever completely accept them, Jamie seems to take it all in stride and Joel straddles the middle, torn between his friends, his more traditional values and his loving fiancée.
