For me, the collar points don't seem especially long - it's the height of the collar bad or at least how high the collar is sitting (relative to his neck) in that particular shot.
I see what you're saying. While it's definitely a little higher than Clooney's or Damon's, it doesn't seem over the edge especially if looking at the back of the neck in relation to the suit collar...1/2" showing on all 3. Maybe they were going for some kind of effect or it might just be the shot
Pitt's character always seemed to dress kind of out there in the Ocean's movies...doesn't he wear those uber-Eurotrashy pointed shoes in these films?
