Here's a rarity. An original rare CBS promotional film highlighting the forthcoming TV premiere of "Hogan's Heroes" a half century ago. You'll note the film also includes cameos by Fred MacMurray of "My Three Sons" and Alan Hale Jr. and Bob Denver of "Gilligan's Island". You'll also notice that the early version of the opening credits is much longer than the final version for broadcast and that there are some cast discrepancies as well.
