Bonanza: The Return

None of the characters from the original series appears since the entire cast, with the exception of Pernell Roberts and David Canary, were dead. Michael Landon Jr. and Dirk Blocker, sons of the original series' stars, do appear, although Blocker, who looked and sounded almost exactly like his father, was cast in a different, smaller role but his face and voice were featured prominently in the commercials advertising the film. Bonanza: The Return was followed two years later with the TV-movie Bonanza: Under Attack. David Canary, who portrayed Candy Canaday on the original series, was not involved with either TV-movie.
