Continuity: When Victoria orders everyone to put up their hands, Illya's left coat sleeve is covering his watch in full shots, but is several inches lower, exposing the watch, in all the close-ups.

Continuity: During the fight in the secret vault, Illya's boots change color, from black to white (they're suddenly white in the close-up when the bad guy reaches out to trip him) and then back to black again.
