Continuity mistake: Ari during the break from the party begins her seductive scheme; posing as a waitress at this guy's own engagement party, she approaches him while he is -for some reason - in the parking lot, makes him smoke a joint for the first time in front of his car, and kisses him - apparently all of this is super easy, barely an inconvenience. When she touches his face, she lowers her fingers from the chin at least 3 times in separate shots when she is whispering things to him. (00:11:50)
Continuity mistake: Michelle Pfeiffer's costume. First we see her toes being painted, drying with tissue between each of her toes.

She never put on any socks or pulled out the tissue.
