Incidentally, while it's conceivable that Nichols and co. weren't thinking of Labute while making the film (although given his extensive work in the theatre, it's hard to believe that Nichols wasn't at least aware of his work), the important thing is that I was thinking of Labute while watching it. Whether coincidental or not, the enormous overlap in subject matter, structure, and style makes a comparison between Closer and Your Friends and Neighbors all but inescapable, and it's not a comparison that favours the former.
