Not only is Sandra Bullock a great actress, but she also apparently has a heart of gold. When an extra on her movie set fainted while filming, Bullock reportedly swooped in to help take care of the fallen woman.

On Sunday, a female extra fainted during an outdoor shoot of the film Our Brand Is Crisis, which stars Bullock. The Academy Award winner reportedly sat beside where the woman had fallen on the concrete and helped give her extra water. Bullock also fanned the woman until an ambulance arrived at the scene. The woman was believed to have suffered from heatstroke and was brought to a hospital for treatment.

Bullock’s co-star, Billy Bob Thornton, was also on the scene, but stood a little apart from the group attending to the woman. Bullock is currently filming Our Brand Is Crisis in Louisiana, which has recently been experiencing high temperatures. The temperature in New Orleans, Page Six reported, reached 82 degrees on Monday. The actors, including Bullock, and extras were required to wear warm clothes on set, which may have caused the woman who fainted to feel excessively hot under the Louisiana sun.

Our Brand Is Crisis is based on a 2005 documentary of the same name that featured the use of US political campaign tactics to elect Gonzalo Sanchez de Lozada as president of Bolivia in 2002. Bullock plays the role of a retired American political consultant, Jane Bodine, hired by Gonzalo to run his campaign, while Thornton plays the part of the opposition’s campaign manager.

The film is produced by George Clooney and helmed by the director of Eastbound & Down and Pineapple Express David Gordon Green. Also starring Scoot McNairy, Anthony Mackie and Ann Dowd, Our Brand Is Crisis is expected to hit theaters in 2016.
