Johnny Depp became a real-life action hero on the set of his movie after saving a group of extras from being struck down by an out-of-control car.

The 44-year old was shooting a scene in his new movie Public Enemies when a stuntdriver in a 1933 Ford car sped onto a patch of ice and skidded towards six extras.

Oblivious to the danger, the extras standing with their backs turned from the car were averted from disaster by the Hollywood hunk who spotted the potentially fatal incident and leapt into action.

An eyewitness tells News Of The World: "Johnny slammed into the group with arms outspread, shoving them all back."

Is there anything Johnny can’t do?
