Continuity: As Mozart is forcing Illya to take him into U.N.C.L.E. HQ's basement, Mozart suddenly acquires, between shots, a security badge that wasn't there before.

Continuity: A swarm of bees blackens the windshield of Solo & Illya's car. We see them in all the interior shots, but every time it cuts to an exterior view, the windshield is perfectly clear.

Visible crew/equipment: The shadow of someone who's not in the shot intrudes on the right side of the screen as Solo exits the communications room and enters the corridor.

Continuity: Mozart and his henchmen invade the honey shop. Illya tosses a chair at them. One man falls. Cut to Illya firing his gun, then back to Mozart - and the man who fell is suddenly in a different place and position on the floor.

Continuity: Tavia writes a receipt and hands it to Mozart. She still has the red pen in her hand until the shot reverses angles. Then the pen instantly jumps from her hand to the counter several inches away.
