Um, the two movies were hardly similar. Just because the guy saw things that weren't there? Aside from it being completely different, I don't know if you knew this, but that's a real person. It's a true story (even if parts were left out). How could the story of a man living with Schizophrenia since the 60's be ripping off Fight Club?

But oh dear, I just realized we're getting back into that mental illness thing. Sure don't want to go there again...
