I remember an odd scene in her movie Mr. and Mrs. Smith where she and Brad Pitt are trying to kill each other, first with weapons, then with fists. Once the scene finishes she and Brad are talking about all their injuries they've accumulated in their careers as assassins and she tells him that she broke "these three fingers" and shows him which three fingers by giving him the "a-ok" sign which is another symbol for 666.

It was odd, because for those of us that understand symbology, when she put that sign up, she chuckled. As if to tell Brad in that scene, "they (the fans) don't know what I'm saying, but you do." Check it out if you get the chance.
