ANGELINA JOLIE terrified her son Pax when she playfully chased him around the MALEFICENT set because she didn't realize how upset he was by her costume.
The actress thought it would be fun to show off her wicked horned outfit to all her kids, but it was far from amusing for young Pax, who ran for his life.
His mom tells Entertainment Weekly, "He ran away and got upset. I thought he was kidding, so I was pretending to chase him until I actually found him crying. I had to take off pieces (of the costume) in front of him to show him it was all fake and not freak him out so much."
