Actress Sandra Bullock rushed to tend to an extra artist on the set of the movie "Our Brand Is Crisis", after the woman collapsed.

The sick lady is said to have fainted due to a heat stroke in New Orleans, Louisiana earlier this week. It was then that the "Gravity" star rushed to help her, reports tmz.com.

Photographic evidence of the scene show Bullock assisting the woman, who was lying on the ground, while on-set medical helpers treated her.

Bullock gave the actress water and even fanned the extra as she was clad in thick clothes in the blazing heat.

An ambulance came later.
