Pitt said of the incident, "I was at the end of the line signing autographs, when out the corner of my eye I saw someone stage-diving over the barrier at me. I took a step back; this guy had latched onto my lapels.”

"I looked down and the nutter was trying to bury his face in my crotch, so I cracked him twice in the back of the head—not too hard—but enough to get his attention, because he did let go,” the actor added.
