Sam Huntington (Superman Returns) will star in ABC's upcoming comedy series Cavemen, which is undergoing some retooling, says The Hollywood Reporter, according to The Hollywood Reporter.

Huntington will play a new caveman character, Andy, who is the younger brother of Joel (Bill English). Andy, who lives in their small hometown, comes to Atlanta to visit his brother after breaking up with his girlfriend.

Andy will replace Jamie, Joel's easygoing little bother character played in the pilot by Dash Mihok.

Inspired by the popular Geico insurance commercials, Cavemen will continue to revolve around three modern cavemen -- Joel, Joel's younger brother and Joel's cynical best friend Nick (Nick Kroll) -- as they struggle to fit in the human-dominated society.

The ABC Studios-produced Cavemen will not launch with the pilot but with another yet-to-be-filmed first episode, which is said to be delving more into the cavemen's backstories.

The original pilot (with Jamie's scenes reshot) is expected to air later in the season.
