I saw it (hard to believe this movie is almost 15 years old!) and yes, Huppert gave an incredible performance. I remember it being disturbing and something I didn't feel like I would be watching on DVD over and over again. Still, I can remember some of scenes/images quite vividly, especially that scene in the bathroom and the final moments. Powerful stuff.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
