Ahhh, that must be why Hogans Heroes was so realistic - damned near a documentary in fact!!
Just kidding - GREAT show! And FTR, the monocle and riding crop of Colonel Klinks? Those were affects that the actor, Werner Klemperer, added himself.
The point being, some of the cast members had more than enough real-life credibility to be playing those characters. Can’t say that about too many actors today, especially ones in ridiculous war films.
