The actress fainted while on the set of Salt last month.
While filming the spy drama, where she plays a Russian spy, Jolie collapsed during an action scene.
"It all got too much for Angelina. She collapsed between takes, complaining of shortness of breath and dizzy spells. To be fair, it was after she’d filmed a strenuous scene in which she ran around the set, but it was still shocking to see her crumble," a source revealed to Britain’s Now magazine.
