The 47-year-old father of six was filming a scene for his new movie World War Z in Glasgow, Scotland Thursday when one of 700 extras stumbled to the ground and was nearly trampled.
"Lots of people hurt themselves and Brad came to the rescue of one woman who slipped," a set source told The Scottish Sun. "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."
The woman wasn't the only extra who was injured during the intense World War Z shoot. "Loads of extras suffered bumps and scrapes during the battle scene," the set insider revealed. "An extra playing a soldier was even hit by a moving car, ending up on the vehicle's bonnet, but fortunately he escaped unhurt."
