Continuity: When Mr. Dulaine forces Rock and LaRhette to dance the waltz together, he takes off his necktie and blindfolds LaRhette with it. Throughout the scene the blindfold is different nearly every time the camera angle changes - the "tail" created by the wide end of the tie gets longer and shorter, the knot alternately loosens and tightens and moves from side to side across the back of her head, and the whole thing slides up and down her nose. It's so distracting I spent the whole scene watching to see how it was going to move next.

Continuity: When Rock is meeting the crooks to receive/pass stolen goods, the van's backdoor opens and guys jump out. A few seconds later, the van door opens again and the same guys jump out.
