Revealing mistake: When Bond rescues Domino from being sold, and she hops on the horse, Kim Basinger is replaced by an obvious stunt.
Continuity mistake: Domino grabs the pendant with her hand positioned sideways. In the close-up, the palm of her hand is face up. Then it swaps to the previous position.
Continuity mistake: When Nigel falls in the water, his hairstyle changes between shots. Sure there's a two seconds shot in between, but that would mean that Nigel had that short lapse to let go his suitcase, bend his head backwards, comb his hair and grab onto his suitcase again... Impossible.
Revealing mistake: During the shoot-out, all the baddies' heads and hands are bare, except for the one that gets burnt alive, who wears very obvious fireproof hood and gloves.

A moment later we see the player putting the taken queen aside but numerous pieces have moved, including two knights and several pawns. (00:03:05)
