Just after Schultz leaves to help General Burkhalter 'with his boots', Klink is standing by the door, talking with Gertrude. He moves toward Gertrude, saying, "Wilhelm, my first name?" As he walks toward Gertrude, the camera swings around to show both of them, causing the shadow of the camera to cross Klink's right elbow and forearm.
When Hogan and Klink are discussing how to handle Gertrude, Hogan says, "... They can't stand being neglected for anything." The view changes to Klink, and he says, "Oh, I see. I'm too involved in my work to find time for her." During Klink's lines, the reflection of the stage light is quite visible in his monocle.
During the denouement, as Klink, Hogan, and Burkhalter are talking, Klink is shown, and says, "I was?" Then, the view shifts to a close-up on Hogan, and he says, "He knows he's not good enough for the Burkhalters." Right as he starts the line, Hogan steps to his left, and the camera shifts to show both Hogan and Burkhalter. During the shift, Hogan is holding his cap in his hands, in front of his waist, and the shadow of the camera crosses Hogan's cap.
