Continuity mistake: Arthur is talking to the police, posing as Naomi's fiance: one of the cops asks, ridiculing her lie, "You had your first date at Grand Central Station?" Behind him, a white haired man in a black suit walks down the street carrying a brown suitcase. Next time the policemen are in frame, a different crowd is on the sidewalk, and only after another cut, and more of Arthur's blabbering, suitcase man reappears as if nothing happened. Even better, over half a minute passes and many totally different people...but right at the end of the scene as the policemen wave Arthur goodbye the same man, sans suitcase this time, is there again walking the same way as before.
