Receiving more fan mail than any other cast member, Landon negotiated with executive producer David Dortort and NBC to write and direct some episodes. In 1962, Landon wrote his first script. In 1968, Landon directed his first episode. In 1993, "TV Guide" listed Little Joe's September 1972 two-hour wedding episode ("Forever") as one of TV's most memorable specials. Landon's script recalled Little Joe's brother, Hoss, who was initially the story's groom, before Dan Blocker's death. During the final season, the ratings declined, and NBC canceled "Bonanza" in November 1972. The last episode aired on January 16, 1973.
