Brad Pitt plays real life hero

Brad Pitt's being playing a real-life action hero on the set of his new movie World War Z.

Pitt who has been filming in Scotland saved an extra who stumbled during the filming of a scene involving 700 extras and came close to being trampled.

A source told The Scottish Sun, "Lots of people hurt themselves and Brad came to the rescue of one woman who slipped. I don't think she could believe it when Brad picked her up.

"He didn't have time to speak to her as it was mid-shoot. But she said afterwards how grateful she was, despite having a badly grazed knee."
