It was while performing a stunt that Angelina Jolie was injured in the face (between her two eyes).  When (real) blood started gushing on the set of her upcoming movie Salt, the producers stopped the camera roll and examined the actress:

“This morning, while filming an action sequence during production of her new movie Salt, Angelina Jolie sustained a minor injury. As a precautionary measure, Ms. Jolie will be taken to the hospital and examined. Production on the film has resumed.”

Good thing she’s back to filming.
