Robert Clary was sick during part of the filming of this episode so Stewart Moss was brought in to film a couple of LeBeau's scenes.
No Names Please (1968) opens with a montage of actual wartime aerial footage that depicts, in quick succession, a flight of American B-17 Flying Fortress four-engine bombers, two German Messerschmitt Bf 109 single-engine fighters, a close-up of one Bf 109, and a German Messerschmitt Bf 110 twin-engine fighter-bomber. The Bf 110 is under attack, presumably by the Bf 109, although the close-up of the fighter doing the firing shows the barrels of two 20 mm cannon mounted in the wing, which neither of the previous shots of the Bf 109s had.
Richard Erdman plays the newsman Walter Hobson who is saved by Hogan and then later writes about it in an American newspaper, which Major Hochstetter subsequently finds out about. Erdman also played a lead character in Stalag 17 (1953) and was the only actor to appear in both that movie and this TV series.
The older of the two new German guards (Private Holtz) is played by the same actor who played Schnitzer's father in a previous episode. He was not included in the credits as he had no speaking lines; he just stood there.
