Well, now that we've seen the rough cuts of the fall pilots, it was inevitable that we'd now be in the recasting phase of the summer. We've already seen changes on a number of shows, and now we can add Cavemen to the list. The Hollywood Reporter is reporting that the highly-anticipated ABC sitcom, which is based on the popular Geico ads, is rethinking one of the main roles.

The role of the younger brother to main character Joel will be renamed from Jamie to Andy, and Dash Mihok, who played the dim-witted but easy-going Jamie in the pilot (he's the guy with the cowboy hat in the picture above), will be replaced by Sam Huntington. He'll play Andy, who leaves his hometown and bunks with Joel after breaking up with his girlfriend.Another interesting bit of news: the pilot we saw will air -- with Jamie's scenes re-shot -- but later in the season. A whole new first episode will air when the show premieres in the fall.

Huntington, by the way, is probably best known for playing Jimmy Olsen in Superman Returns, but since he'll be under all that caveman hair and makeup, I'm pretty sure fans of that movie won't really recognize him.
