Brad Pitt may have starred as the imaginary hero in many a woman's dreams, but for one lucky lady, fantasy became reality on the set of the film "World War Z."

The unidentified extra was one of hundreds taking part in a scene featuring Pitt and a mass of people running through Glasgow's George Square to flee a zombie invasion. During filming, the woman tripped, fell to the ground, and nearly faced serious injury if not for Pitt scooping her up and carrying her to safety. 

"It was total chaos as 700 extras were trying to get down the street — they were banging into moving cars, cameras and military who were carrying heavy machine guns," a source told The Scottish Sun. "Lots of people hurt themselves, and Brad came to the rescue of a woman who slipped. I don't think she could believe it when Brad picked her up."

According to the article, the mock scene featured some very real injuries, including broken bones, cuts and bruises, and even one extra playing a soldier who was hit by a moving car. He was fortuantely unharmed.

For an example of just how chaotic some of these scenes can be for the extras, check out this clip shot by a bystander in Glasgow of a truck plowing into a series of cars. "World War Z" is slated to hit theaters on Dec. 21, 2012
