Hogan's Heroes is an American television sitcom that ran for 168 episodes from September 17, 1965, to March 28, 1971, on the CBSnetwork. The show was set in a German prisoner of war (POW) camp during the Second World War. Bob Crane had the starring role as Colonel Robert E. Hogan, who coordinated an international crew of Allied prisoners running a Special Operations group from the camp. The program also featured Werner Klemperer as Colonel Wilhelm Klink, the commandant of the camp, and John Banner as the inept sergeant-of-the-guard, Schultz.
The pilot episode, "The Informer", was produced in black-and-white. As with many pilot episodes, there are several differences from the series proper, such as Burkhalter being introduced as a colonel, instead of a general. There were many changes to Larry Hovis's character of Carter. In the pilot, he was credited as a guest star and is shown as a lieutenant, rather than a sergeant. "Lt. Carter" had recently escaped from another camp and at the end of the episode, is en route to England.
Leonid Kinskey appeared in the pilot episode as Vladimir Minsk, a Soviet POW who specializes in tailoring. Kinskey ultimately turned down a contract to become a permanent character, contending that the subject matter was being treated too lightly.
In the pilot, Col. Klink's secretary is actually part of Hogan's team, and she has access to the tunnels. In the actual TV series, she is merely willing to look the other way in exchange for a warm kiss from Hogan, or some other form of affectionate gesture. Eventually, during the run of the TV series, it is implied that she and Hogan have a running romance, especially when she hints at getting a diamond engagement ring in exchange for her help. Another difference is that the word "Stalag" was avoided in the pilot; it was simply referred to as "Camp 13."
The camp also appears to be bigger, with more barracks, prisoners, and guards shown than on the series itself. Klink also appears to have an adjutant.
