When Mark Slade is fighting in the laundry area and the alley he takes a laundry basket out of the van and places it in the alley. On the end of the basket it has writing that says "D.C." However after the fight in the laundry room he returns to the laundry basket in the same place but this time it says "Dry Cleaning." Somewhere along the way they rotated the laundry basket.
April heads back to her desk to listen in on Caresse's phone call. There is a person at a filing cabinet, facing the wall. During the close-up of April, the person is now standing at the side of the cabinet, and then back to the original position later on in the shot.
During the last minutes when Mr. Waverly checks on Illya and Solo the monitor screen changes from a rectangular tube to a round tube screen.
April dabs a cut on Slade's chin with a wet napkin/towel. However, she dabs all around the cut and never actually touches the cut itself, probably due to it being make-up.
In order to make sure that April Dancer's lips with the phosphorescent moon glow would show up on camera, the lipstick was actually painted on a piece of glass that was placed in front of her mouth. This is noticeable as her head wobbled slightly from side to side while her glowing lips remained perfectly still.
