Continuity: The dead guards, who were all over the courtyard after the gun battle, have all disappeared when Solo and Albert return to untie Illya.

Continuity: Solo's white gloves are on, off, and on again between takes as he and Albert run from the courtyard, search for the control room, and then finally go back for Illya.

Continuity: When Illya and Vogler practice shooting arrows at the "No Hunting" sign, the "I" is completely there one moment, then acquires a huge white chip in its base without being hit by an arrow. A few shots later, it's intact again.

Continuity: Vogler paints a target on Illya's shirt back and hunts him. The target remains constant through most of the chase, until a stunt double is brought in for a fight sequence. The double's target has a large "bite" taken out of the bull's eye. The bite goes away after the fight, and Illya's target is whole again.

Continuity: Solo sneaks down an empty corridor and knocks out the only man guarding the lab door. When the camera angle reverses, there's a second unconscious (or dead) man on the floor behind him. Where'd that guy come from? Solo didn't encounter anyone before the door guard, and there were no bodies already on the floor when he entered the hall.

Continuity: While he's running through the woods with his hands cuffed behind him, Illya's sleeves alternate, between shots, from pushed up above his elbows to pulled all the way down to his wrists.
