Ponderosa Ranch "Bonanza" episodes were shot at the theme park's Virginia City site, although the town was prominently featured in three "Bonanza" television movies. Because the movies showcased the next generation of Cartwrights, they began circa 1905. The Ponderosa park expanded beyond the buggy era to include an exhibit featuring antique cars. It was a fledgling endeavor as tourists wanted to see horses flanked by Cartwright saddles. The idea for the theme park came about in 1965. Bill and Joyce Anderson owned a small horse ranch, which is located in about the same area as the fictional Ponderosa on the burning map.
Bonanza: The Next Generation Bonanza: The Next Generation Bonanza: The Next Generation is a 1988 American made-for-television western film and a sequel to the 1959–1973 television series "Bonanza" starring John Ireland, Robert Fuller, Barbara Anderson, Michael Landon Jr., Brian A. Smith and John Amos. None of the characters from the original series appears since the entire cast, with the exception of Pernell Roberts and Michael Landon, had died. Lorne Greene had signed to reprise his role as patriarch Ben, but died shortly before production began. He was replaced by veteran actor John Ireland, who played Ben's brother Aaron. The movie features Michael Landon Jr.
