AAfter Bateman has had sex with Christie (Cara Seymour) and Sabrina (Krista Sutton), they are all lying together in bed, when he gets up and moves over to a drawer. He opens it, revealing a number of sharp metal items. He pulls out a coat-hanger and tells the prostitutes that they aren't finished yet. The scene then cuts to Sabrina and Christie walking out of Bateman's apartment; Sabrina is cut, limping, bruised and bleeding, we don't see Christie's face, but we do learn later that whatever happened, she had to attend casualty.It is revealed in neither the book nor the film what exactly Bateman does to the girls. In the novel, the corresponding scene reads:
I awaken only when one of them touches my wrist accidentally. My eyes open and I warn them not to touch the Rolex, which I've kept on during this entire time. They lie quietly on either side of me, sometimes touching my chest, once in a while running their hands over the muscles in my abdomen. A half hour later I'm hard again. I stand up and walk over to the armoire, where, next to the nail gun, rests a sharpened coat hanger, a rusty butter knife, matches from the Gotham Bar and Grill and a half-smoked cigar; turning around, naked, my erection jutting out in front of me, I hold these items out and explain in a hoarse whisper, "We're not through yet..." An hour later I will impatiently lead them to the door, both of them dressed and sobbing, bleeding but well paid. Tomorrow Sabrina will have a limp. Christie will probably have a terrible black eye and deep scratches across her buttocks caused by the coat hanger. Bloodstained Kleenex will lie crumpled by the side of the bed along with an empty carton of Italian seasoning salt I picked up at Dean & Deluca.
ANo. All the songs that were used in the film were used legally. The issue of illegality came about in relation to the soundtrack. When the American Psycho: Music From The Controversial Motion Picture was initially released, it included all the songs heard in the film. However, within a few days, it transpired that Koch Records, the publishers of the soundtrack, hadn't obtained the publishing rights to 'Hip to Be Square' by Huey Lewis & The News (separate rights needed to be acquired for each song; one for the movie and another for the soundtrack). The CD was immediately recalled (although a few thousand had already sold), and replaced with a new CD without that particular song on it. Over the years, this has built up into a myth that Lewis objected to the use of his song when he saw the film, and demanded that it not be included on the soundtrack. As Mary Harron discusses on her DVD commentary, there is no truth in this, the song is absent purely because of publishing rights.An article about the issue can be found here.
