KING OF PRUSSIA, Pa., (CBS) – Brad Pitt made a surprise appearance at a movie theater in King of Prussia Thursday night.

The actor shocked fans during a screening of Pitt’s new film World War Z at the Regal Cinema.

The movie is set in Philadelphia, but was shot in Scotland.

The movie-goers certainly got more than they bargained for.

“Two ladies that ended up sitting next to us had been down where he was coming in and they had them move and they told them that he was coming, and so we thought, oh, there’s just fooling them   – and then he walks in,” said Larry Moton of Philadelphia.

“It was the biggest surprise of my life. It was amazing. And it just enhanced how perfect the movie was,” said Rachel Nichols of Gladwyne.
