Actress Angelina Jolie was taken to hospital on Friday after suffering a head injury while on set for her latest film, movie bosses have said. The 33-year-old was shooting an action sequence for upcoming thriller Salt in New York when she suffered "a minor bump to the head". Columbia Pictures spokesman Steve Elzer said Jolie was taken to a local hospital as a "precautionary measure". He added she was back on set later that day and production had resumed. Salt sees Jolie star as a CIA officer who goes on the run after being accused of being a Russian sleeper spy. It had been reported last year that the role had been initially earmarked for Hollywood actor Tom Cruise, and that the script and title were reworked after Jolie became involved in the film. The movie, which also features X-Men Origins: Wolverine star Liev Schreiber and British actor Chiwetel Ejiofor, is due to be released in cinemas in the summer of next year. Source: BBC
