Bonanza, the single most successful television series of the 1960s (and, at 13 1/2 seasons, second only to Gunsmoke for network TV’s longest-running Western), created and produced by David Dortort and starring Lorne Greene, Pernell Roberts, Dan Blocker, and Michael Landon, has been lovingly and painstakingly restored and remastered for CBS’s and Paramount’s fabulous DVD boxed set, Bonanza: The Official Complete Series. The hefty set—112 discs in four chunky volumes—was executive produced by Andrew J. Klyde, and his results are spectacular: all 431 full-length episodes have been digitally remastered (including the problematic Season 2 transfers previously released) from the original 35mm color film camera negatives, complete with original music…and with a ridiculous amount of incredibly rare, fascinating bonus material included on this set. It’s an astonishing work of television preservation.
