text: Season 10 As of the season 10 premiere, there was another major overhaul of the crew, with Leonard Katzman not only returning to the production side of the show but also getting promoted to executive producer, reportedly on the condition that he would get "total authority" of the show, while Philip Capice and most of the season 9 staff left the production. Alongside Katzman, David Paulsen was brought back as the show's new producer, while the position as supervising producer was offered to newcomer Calvin Clements Jr. and Cliff Fenneman remained associate producer. A new writing staff was hired to work alongside the producers, including Katzman's son Mitchell Wayne Katzman as story editor and Leah Markus as story consultant. Markus left after two years, while the others remained until the show's end.
  Scriptwise, Patrick Duffy's return was explained by having the entire season 9 being a dream of Victoria Principal's character Pam, effectively sweeping away the events occurring during the period in which Katzman's involvement with the show had been minimized.
  Even the cast were affected by the production and political struggles. While Larry Hagman (J.R.) reportedly supported Katzman, and had played a great part in bringing Duffy back, Susan Howard (Donna), who also had written the script for one of the season 9 episodes, had sided with Philip Capice, and was opposed to the idea of annulling the events of season 9. While she returned to write another episode for season 10, she left the show, both as a writer and as a cast member, at the end of the season.
