Even though this was episode number 16 in broadcast order, it was one of the first produced (serial 5784-05). Burkhalter is listed as Colonel in credits, just like he was in the pilot. The men also act like they have never met him. Sgt. Carter has to ask a couple of times for his correct name.
Although Hogan did toy with Klink's Pickelhaube helmet throughout the series, Carter is the only one to ever be seen wearing it in this episode.
When Hogan is on the radio to 'Papa Bear' discussing the plans for Michael's escape, 'Papa Bear' is actually being voiced by Richard Dawson.
In this installment, it is mentioned that STALAG 13 is located 60 miles from the North Sea. This contradicts several mentions of the Stalag residing close to Hammelburg, which is located several hundred miles from the sea.
Michael St. Clair, who plays Capt. Michaels in this episode, would later guest star in another WWII episode, Invasion (1966).
