Why has no one addressed the mannequins perfect understanding and speaking of modern american english though she was supposed to be German. I think it would have been funny for her to come alive confused and screaming in german, but maybe thats just me. And the lack of accents in the first scene. Also that the guard that gets stabbed in the foot has on what looks like rubber boots.
Another issue I had was how in the dance scene the female dancers morphed into completely different outfits and hairstyles.
Lastly, they do make mannequins that are anatomically correct, but why would that matter? In the movie someone points to the fact that she is hollow and knocks on her.
