'Unbroken' star Jack O'Connell inspired Angelina Jolie to learn Derby dialect

Angelina Jolie has been learning how to speak Derbyshire dialect after being fascinated by her 'Unbroken' star Jack O'Connell.

The 39-year-old actress, who made her directorial debut on a big-budget blockbuster, which portrays O'Connell as World War II hero Louis Zamperini, had picked up the dialect of the Derby actor on the sets, after which she decided take lessons for it, the Daily Star reported.

Brad Pitt's wife, who has just recovered from chickenpox, and her film crew also learnt not to mess about with O'Connell's way of speaking as well.

Japanese rocker Miyavi, 33, who co-stars in the film, said that though it was easy to understand when the 24-year-old actor spoke with US east coast accent during shoot, as soon the cameras stopped rolling, he used to go back to his native accent, for which a dialect expert was needed on hand all the time.
