The real problem here is that the trailer was intentionally misleading to get more people to see it. This movie never intended to be AHX or Fight Club..
No it wasn't, Norton/De Niro banters made up half of the trailer and Norton/De Niro banters were exactly what we got. The other half of the trailer was the affair and we got that too.
And I never said it was intended to be AHX or Fight Club or expected that. Because AHX is by far Norton's best role, when you see Norton playing a thug, initially you can't help but think about his character in AHX. That has nothing to do with the actual story.
