A "Brady Bunch" tell-all revealed how Mike Lookinland (Bobby) wound up on the dark-haired Brady boys team. The casting-agent-turned-author explained that he wanted the boys to have the same color hair as the father. Once brunette Bob Reed was chosen to play the patriarch, the die – or, in this case, dye -- was cast. Brunette boys were hired to play the two older brothers. Six-year-old Lookinland was clearly the best actor of the youngest boys – despite his flaxen locks -- so he was hired and his hair was darkened. (ABC Photo Archives/Getty Images)
