Starring: Bob Crane, John Banner, Robert Clary, Werner Klemperer
To Russia Without Love - S6-E18
Revealing mistake: As the motorcycle and the side car split apart and drive around independently, you can see that the side car has been given two extra wheels, and some other stuff underneath as well that's not present on regular Wehrmacht BMW sidecars - probably a remote control of sorts. Also, the motorcycle Schultz rides has training wheels mounted in the shot where the side car comes off.
Hogan Gives a Birthday Party - S2-E1
Continuity mistake: The footage of the bomber's nomenclature Hogan and his men commandeer switches several times from during the takeoff, the bombing run, then the end of the bombing run - three different types of planes.
Trivia: When Klink is begging Hogan to trade places with him for fear of assassination, he says to him something like."I want to live til 80...all my family has lived til 80." Werner Klemperer, who played Klink, passed away in 2000 aged 80.
