Nice , nice move WB by releasing this AFTER the worldcup.
Every studio knows just how big football tourmaments like the worldcup or Eurocup can be done and just how much it can affect sales outside north america.
As for Pirates hurting it , we'll have to wait and see. The last Pirates movie definately didn't set the BO on fire in the states and unless they up the ante in terms of spectacle , chances are the last movie might've also left a sour taste in peoples mouth.
What WB needs to do is just market the hell out of this movie
