Zoe Saldana is apparently an action hero on screen and in real life.
The Avatar star, 33, rushed to the aid of an elderly woman who had reportedly gotten into a car accident in Culver City, Calif., on Wednesday afternoon.
"Zoe witnessed the accident and was so quick to help," says an onlooker. She "immediately got on the phone with 911 and seemed very concerned."
The actress, reportedly dating Bradley Cooper, and another passerby transported the woman – who was conscious but injured – from her car to the curb.
They called 911 and waited for police and paramedics on the scene.
The onlooker also told People: "While waiting for help to arrive, Zoe returned to the woman's car and picked up the woman's handbag and sweater."
"Zoe was very caring and sweet to the woman."
