Ed Benedict provided uncredited layout designs for this cartoon. Benedict would later work for Hanna-Barbera Studios (which was started by MGM alumni William Hanna and Joseph Barbera), where he would use some of the caveman designs from this cartoon as the basis for characters in "The Flintstones".
