Continuity: In close-up, the brainwashed Illya holds the Luger at an angle, close to his face. But when the shot cuts, he's suddenly holding it straight and much lower, level with his chest. Next close-up, it's back in the original position again.

Visible crew/equipment: When Solo and Coleman call Monica from the hotel, the shadow of the entire boom mike assembly is bobbing up and down on the wall above and behind them.

Continuity: The dust on Illya's tux lapel cleans itself off between takes when he pulls Monica out of the casino.

Continuity: Solo leaps from a roof, appears to get shot, and lands on his back with his tie flipped up over his face and his coat hiked up. In the very next shot, though, his tie and coat have both straightened themselves out nicely, and his arms have completely changed positions.
