Bateman's dragging Paul's body stuffed in a bag across the building's lobby, the shot from the back shows a long trail of blood while both shots from the front show not a trace.
But we find out later in the film that Patrick never really killed Paul; he merely imagined it. Could he not have imagined this too, as part of his sick little fantasy?
Even though it was his sick little fantasy you couldn't see blood or any other fluid from the front view of him or anybody else. In the movies or in real life.
This is a slip-up. The killings weren't in his head. Read the book. This is a satire of the late 80s. It's about yuppies in New York, how everyone is too caught up in themselves to notice anything else. Again, read the book, it's brilliant.
Actually, Meglocrush, I have read the book, and it is absolutley certain that none of what Patrick believes is happening is really happening. I do agree with you on the brilliance of the book however, and I have written quite a few papers on the subject. The dissapearing blood is not a slip-up, it is a direct reference to the delusion that is Patrick's mind.
Found this and thought it would be helpful.
Co-writer Guinevere Turner stated this in this interview excerpt:
GT: All the killings that happen in American Psycho are real. Those characters certainly did die. But if they don't seem real it's because some of the details exist only in the mind of Patrick Bateman. He glamorizes the murders and it is
through his eyes that the story is told.
The blood trail might be a slip up, or it might not be. It could just be showing how no one would notice because everyone is so caught up in themselves.
