Zoe Saldana swooped in to help an elderly woman who was left badly bruised following a car accident on Wednesday (18Jan12).
The Avatar star rushed to the victim's side and escorted her out of harm's way and onto a nearby curb after witnessing the crash in Culver City, California.
An onlooker tells People.com Zoe Saldana was "very quick to help" adding, "(She) immediately got on the phone with 911 and she seemed very concerned. 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."
Photos of the scene, which have been posted online, suggest the woman was conscious but in pain after suffering minor facial injuries.
