Charlie's Angels: Season Two was the second season of the TV series Charlie's Angels. Three cast members from season one returned: Kate Jackson, Jaclyn Smith and David Doyle. This season saw the introduction of Cheryl Ladd as Kris Munroe, the younger sister of former Angel Jill Munroe. Season Two originally aired from September 14, 1977 to May 10, 1978, and proved just as a major success as Season One. There were doubts as to whether Ladd could fill the void left by Fawcett-Majors; however, after a few bikinis and tight clothing Kris was warmly welcomed. Co-star Jaclyn Smith said of Ladd: "she had big shoes to fill and she did it with confidence." With Ladd being accepted as Kris, ratings finished in the #4 slot for the season. Although not an original character, Kris gained fame and popularity equal to the original Angels, leading her to become a major character of the series, and several episodes were centered around her. This is in stark contrast to other replacement Angels, Tiffany Welles and Julie Rogers, who were not seen as major characters and appeared only briefly in some episodes. Althoug not have a properly time screen Tiffany gained a lot of popularity too in her season debut.
