Continuity mistake: During the dance sequence for "That's the Way (I Like It)" Kelly's shoes change twice: at the beginning she is wearing open-toed black shoes, then she is wearing sneakers for about two seconds, then back to the open-toed shoes and finally to the sneakers for the remainder of the scene. (01:13:25)
Continuity mistake: In the last scene Gareth Gates was a clone but he had a belly button and the clones didn't have them.
Continuity mistake: When Ellen is getting up from the table after arguing with Jill, she takes her purse off the table with her right hand. In the next shot, she's shown dragging her purse across the table with her left hand.
Continuity mistake: When Shanti rubs the war make-up off Ranjan's face, she only rubs half the make-up off. In the next shot, all the make-up is gone.
Continuity mistake: Look at the scene where Chanel and her mom are putting on face cream. In the wide shot, Chanel only has cream on her chin, cheeks and forehead. Her mom hasn't applied the cream. In the close-up (when her mom says that they might be moving to Paris), there's cream all over their faces.
