Imagine going to the theater and in walks the star of the movie. It happened in Philadelphia and Atlanta as Brad Pitt surprised audiences at screenings of his new movie 'World War Z.'

He hit a theater in Atlanta yesterday morning, then he popped up at show in Philly last night.

The distance between the two theaters is 778 miles, or about a 12 hour drive. But it's only a two hour flight from Atlanta to Philly.

Watch the trailer for World War Z.
