text: Season 13 saw several additions to the main cast: Academy Award winner George Kennedy as Carter McKay, who buys Ray's ranch and eventually becomes the head of Ewing Oil rival WestStar; Cathy Podewell as the young and naïve Cally Harper Ewing, J.R.'s second wife, whom he married to escape false rape charges; Sasha Mitchell as J.R.'s illegitimate firstborn son, James Beaumont; Kimberly Foster as April's devious sister Michelle Stevens, who marries both James and Cliff Barnes; and finally Lesley-Anne Down as PR woman Stephanie Rogers. While Kennedy and Podewell had appeared regularly throughout season 12, Mitchell, Foster and Down's characters were all new to the series when they joined the regular cast.
  Finally, for the 14th and final season, after guest starring in the last episodes of season 13, Barbara Stock joined the cast as Cliff's fiancée Liz Adams.
